表格展示，不支持配置初始化接口初始化数据域，所以需要搭配类似像`Service`这样的，具有配置接口初始化数据域功能的组件，或者手动进行数据域初始化，然后通过`source`属性，获取数据链中的数据，完成数据展示。

## 基本用法

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
        {
            "type": "table",
            "title": "表格1",
            "source": "$rows",
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine"
                },

                {
                    "name": "version",
                    "label": "Version"
                }
            ]
        }
    ]
}
```

## 数据需求

数据是对象数组，比如前面的例子中 `rows` 的值类似：

```
[
    {
        "engine": "webkie",
        "version": 1
    }
]
```

## 列配置

`columns`内，除了简单的配置`label`和`name`展示数据以外，还支持一些额外的配置项，可以帮助更好的展示数据。

### 列类型

除了简单展示数据源所返回的数据以外，`list`的列支持除表单项以外所有组件类型，例如：

```schema
{
    "type": "table",
    "data": {
        "items": [
            {
                "id": "91264",
                "text": "衡 阎",
                "progress": 22,
                "type": 4,
                "boolean": true,
                "list": [
                    {
                        "title": "Forward Functionality Technician",
                        "description": "nisi ex eum"
                    },
                    {
                        "title": "District Applications Specialist",
                        "description": "ipsam ratione voluptas"
                    },
                    {

        {

                "2": "<span class='label label-success'>开心</span>",
                "3": "<span class='label label-danger'>惊吓</span>",

            "placeholder": "-",
            "listItem": {
                "title": "${title}",
                "subTitle": "${description}"
            }
        }
    ]
}
```

### 列宽

可以给列配置 `width` 属性，控制列宽，共有两种方式：

#### 固定像素

可以配置数字，用于设置列宽像素，例如下面例子我们给`Rendering engine`列宽设置为`100px`。

```schema: scope="body"
{
    "type": "crud",
    "api": "/api/mock2/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "width": 100
        }
    ]
}
```

#### 百分比

也可以百分比来指定列宽，例如下面例子我们给`Rendering engine`列宽设置为`50%`。

```schema: scope="body"
{
    "type": "crud",
    "api": "/api/mock2/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "width": "50%"
        }
    ]
}
```

### 列对齐方式

> 1.4.0 及以上版本

通过 align 可以控制列文本对齐方式，比如

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
      {
        "type": "table",
        "title": "表格1",
        "source": "$rows",
        "columns": [
          {
            "name": "engine",
            "label": "Engine"
          },
          {
            "label": "Version",
            "type": "tpl",
            "tpl": "${version | number}",
            "align": "right"
          }
        ]
      }
    ]
}
```

### 列样式

> 1.4.0 及以上版本

除了前面的宽度和对齐方式，还有更灵活的控制方法是通过样式表

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
      {
        "type": "table",
        "title": "表格1",
        "source": "$rows",
        "columns": [
          {
            "name": "engine",
            "label": "Engine"
          },
          {
            "name": "version",
            "label": "Version",
            "className": "text-primary"
          }
        ]
      }
    ]
}
```

如果要单独设置标题的样式，可以使用 `labelClassName` 属性

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
      {
        "type": "table",
        "title": "表格1",
        "source": "$rows",
        "columns": [
          {
            "name": "engine",
            "label": "Engine"
          },
          {
            "name": "version",
            "label": "Version",
            "className": "text-primary",
            "labelClassName": "font-bold"
          }
        ]
      }
    ]
}
```

### 单元格样式

> 1.4.0 及以上版本

`classNameExpr` 可以根据数据动态添加 CSS 类，支持 [模板](../../docs/concepts/template) 语法。

例如下例，`"<%= data.version > 5 ? "text-danger" : "" %>"` 表示当行数据的 `version` 数据大于 5 的时候添加 `text-danger` CSS 类名，使得文字颜色变红

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
        {
            "type": "table",
            "source": "$rows",

            "columns": [
                {
                    "name": "engine",
                    "label": "Engine"
                },
                {
                    "name": "version",
                    "label": "Version",
                    "classNameExpr": "<%= data.version > 5 ? 'text-danger' : '' %>",
                },
                {
                    "name": "grade",
                    "label": "Grade"
                }
            ]
        }
    ]
}
```

### 背景色阶

> 1.8.0 及以上版本

`backgroundScale` 可以用来根据数据控制自动分配色阶

```schema: scope="body"
{
    "type": "service",
    "data": {
        "rows": [
            {
                "engine": "Trident",
                "version": "1",
                "grade": "A"
            },
            {
                "engine": "Trident",
                "version": "7",
                "grade": "B"
            },
            {
                "engine": "Trident",
                "version": "4",
                "grade": "C"
            },
            {
                "engine": "Trident",
                "version": "3",
                "grade": "A"
            },
            {
                "engine": "Trident",
                "version": "4",
                "grade": "A"
            },
            {
                "engine": "Gecko",
                "version": "6",
                "grade": "A"
            },
            {
                "engine": "Gecko",
                "version": "2",
                "grade": "A"
            },
            {
                "engine": "Gecko",
                "version": "5",
                "grade": "B"
            },
            {
                "engine": "Gecko",
                "version": "10",
                "grade": "D"
            }
        ]
    },
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine"
                },
                {
                    "name": "version",
                    "label": "Version",
                    backgroundScale: {
                        min: 0,
                        max: 10,
                        colors: ['#FFEF9C', '#FF7127']
                    }
                },
                {
                    "name": "grade",
                    "label": "Grade"
                }
            ]
        }
    ]
}
```

`min` 和 `max` 都支持变量，如果为设置会自动计算当前列的最大和最小值。

默认会从当前列的 `name` 属性来获取数据，也可以通过 `backgroundScale.source` 使用变量及公式来获取数据。

### 默认是否显示

默认 `columnsTogglable` 配置为 `auto`，当列超过 5 列后，就会在工具栏多渲染出来一个列展示与否的开关。你可以设置成 `true` 或者 `false` 来强制开或者关。在列配置中可以通过配置 `toggled` 为 `false` 默认不展示这列，比如下面这个例子中 ID 这一栏。

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "className": "m-b-none",
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine"
                },

                {
                    "name": "grade",
                    "label": "Grade"
                },

                {
                    "name": "version",
                    "label": "Version"
                },

                {
                    "name": "browser",
                    "label": "Browser"
                },

                {
                    "name": "id",
                    "label": "ID",
                    "toggled": false
                },

                {
                    "name": "platform",
                    "label": "Platform"
                }
            ]
        }
    ]
}
```

### 固定列

列太多可以让重要的几列固定，可以配置固定在左侧还是右侧，只需要给需要固定的列上配置 `fixed` 属性，配置 `left` 或者 `right`。

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "className": "w-xxl",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "className": "m-b-none",
            "columnsTogglable": false,
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine",
                    "fixed": "left"
                },

                {
                    "name": "grade",
                    "label": "Grade"
                },

                {
                    "name": "version",
                    "label": "Version"
                },

                {
                    "name": "browser",
                    "label": "Browser"
                },

                {
                    "name": "id",
                    "label": "ID"
                },

                {
                    "name": "platform",
                    "label": "Platform",
                    "fixed": "right"
                }
            ]
        }
    ]
}
```

### 可复制

可以在列上配置`"copyable": true`，会在该列的内容区里，渲染一个复制内容的图标，点击可复制该显示内容

```schema: scope="body"
{
    "type": "crud",
    "api": "/api/mock2/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "copyable": true
        }
    ]
}
```

你也可以配置对象形式，可以自定义显示内容

```schema: scope="body"
{
    "type": "crud",
    "api": "/api/mock2/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "copyable": {
                "content": "复制的内容是：${engine}"
            }
        }
    ]
}
```

### 弹出框（popOver）

可以给列上配置 `popOver` 属性，会在该列的内容区里，渲染一个图标，点击会显示弹出框，用于展示内容

```schema: scope="body"
{
    "type": "crud",
    "api": "/api/mock2/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "popOver": {
                "body": {
                    "type": "tpl",
                    "tpl": "${engine}"
                }
            }
        }
    ]
}
```

popOver 的其它配置请参考 [popover](./popover)

### 表头样式

可以配置`"isHead": true`，来让当前列以表头的样式展示。应用场景是：

1. 所有列`label`配置空字符串，不显示表头
2. 配置`combineNum`，合并单元格，实现左侧表头的形式
3. 列上配置`"isHead": true`，调整样式

```schema: scope="body"
{
  "type": "crud",
  "api": "/api/mock2/sample?waitSeconds=1",
  "affixHeader": false,
  "combineNum": 1,
  "columns": [
    {
      "name": "engine",
      "label": "",
      "isHead": true
    },
    {
      "name": "browser",
      "label": ""
    },
    {
      "name": "platform",
      "label": ""
    },
    {
      "name": "version",
      "label": ""
    },
    {
      "name": "grade",
      "label": ""
    }
  ]
}
```

还可以配置"offset"，实现弹出框位置调整自定义

```schema: scope="body"
{
    "type": "crud",
    "api": "/api/mock2/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "popOver": {
                "body": {
                    "type": "tpl",
                    "tpl": "偏了一点的popover"
                },
                "offset": {
                    "y": 100
                }
            }
        }
    ]
}
```

## 嵌套

当行数据中存在 children 属性时，可以自动嵌套显示下去。

```schema: scope="body"
{
    "type": "service",
    "data": {
        "rows": [
            {
                "engine": "Trident",
                "browser": "Internet Explorer 4.0",
                "platform": "Win 95+",
                "version": "4",
                "grade": "X",
                "id": 1,
                "children": [
                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 4.0",
                    "platform": "Win 95+",
                    "version": "4",
                    "grade": "X",
                    "id": 1001
                },
                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 5.0",
                    "platform": "Win 95+",
                    "version": "5",
                    "grade": "C",
                    "id": 1002
                }
                ]
            },
            {
                "engine": "Trident",
                "browser": "Internet Explorer 5.0",
                "platform": "Win 95+",
                "version": "5",
                "grade": "C",
                "id": 2,
                "children": [
                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 4.0",
                    "platform": "Win 95+",
                    "version": "4",
                    "grade": "X",
                    "id": 2001
                },
                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 5.0",
                    "platform": "Win 95+",
                    "version": "5",
                    "grade": "C",
                    "id": 2002
                }
                ]
            },
            {
                "engine": "Trident",
                "browser": "Internet Explorer 5.5",
                "platform": "Win 95+",
                "version": "5.5",
                "grade": "A",
                "id": 3,
                "children": [

                },
                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 5.0",

                }
                ]
            },
            {

                }
                ]
            },

                "id": 5,

                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 5.0",

                }
                ]
            }
        ]
    },
    "body": [

                }
            ]
        }
    ]
}
```

## 底部展示 (Footable)

列太多时，内容没办法全部显示完，可以让部分信息在底部显示，可以让用户展开查看详情。配置很简单，只需要开启 `footable` 属性，同时将想在底部展示的列加个 `breakpoint` 属性为 `*` 即可。

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "className": "m-b-none",
            "columnsTogglable": false,
            "footable": true,
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine"
                },

                {
                    "name": "grade",
                    "label": "Grade"
                },

                {
                    "name": "version",
                    "label": "Version",
                    "breakpoint": "*"
                },

                {
                    "name": "browser",
                    "label": "Browser",
                    "breakpoint": "*"
                },

                {
                    "name": "id",
                    "label": "ID",
                    "breakpoint": "*"
                },

                {
                    "name": "platform",
                    "label": "Platform",
                    "breakpoint": "*"
                }
            ]
        }
    ]
}
```

默认都不会展开，如果你想默认展开第一个就把 footable 配置成这样。

```json
{
  "footable": {
    "expand": "first"
  }
}
```

当配置成 `all` 时表示全部展开。

## 合并单元格

只需要配置 `combineNum` 属性即可，他表示从左到右多少列内启动自动合并单元格，只要多行的同一个属性值是一样的，就会自动合并。

如果你不想从第一列开始合并单元格，可以配置 `combineFromIndex`，如果配置为 1，则会跳过第一列的合并。如果配置为 2，则会跳过第一列和第二列的合并，从第三行开始向右合并 `combineNum` 列。

```schema: scope="body"

    "type": "service",
    "data": {
        "rows": [
            {

            ]
        }
    ]
}
```

## 超级表头

超级表头意思是，表头还可以再一次进行分组。额外添加个 `groupName` 属性即可。

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=5",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "className": "m-b-none",
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine",
                    "groupName": "分组1"
                },

                {
                    "name": "grade",
                    "label": "Grade",
                    "groupName": "分组1"
                },

                {
                    "name": "version",
                    "label": "Version",
                    "groupName": "分组2"
                },

                {
                    "name": "browser",
                    "label": "Browser",
                    "groupName": "分组2"
                },

                {
                    "name": "id",
                    "label": "ID",
                    "toggled": false,
                    "groupName": "分组2"
                },

                {
                    "name": "platform",
                    "label": "Platform",
                    "groupName": "分组2"
                }
            ]
        }
    ]
}
```

## 高亮行

可以通过配置`rowClassNameExpr`来为行添加 CSS 类，支持 [模板](../../docs/concepts/template) 语法。

例如下例，`"<%= data.id % 2 ? "bg-success" : "" %>"` 表示当行数据的 `id` 变量为 不能被 `2` 整除时，给当前行添加`bg-success` CSS 类名，即绿色背景色

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=10",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "rowClassNameExpr": "<%= data.id % 2 ? 'bg-success' : '' %>",
            "columns": [
                {
                    "name": "engine",
                    "label": "Engine"
                },

                {
                    "name": "grade",
                    "label": "Grade"
                },

                {
                    "name": "version",
                    "label": "Version"
                },

                {
                    "name": "browser",
                    "label": "Browser"
                },

                {
                    "name": "id",
                    "label": "ID"
                },

                {
                    "name": "platform",
                    "label": "Platform"
                }
            ]
        }
    ]
}
```

## 总结行

可以通过配置 `prefixRow` 或 `affixRow` 来为表格顶部或底部添加总结行，

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=10",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "columns": [
                {
                    "name": "browser",
                    "label": "Browser"
                },

                {
                    "name": "version",
                    "label": "Version"
                }
            ],
            "affixRow":[
                {
                    "type": "text",
                    "text": "总计"
                },
                {
                    "type": "tpl",
                    "tpl": "${rows|pick:version|sum}"
                }
            ]
        }
    ]
}
```

### 配置合并单元格

可以配置 `colSpan` 来设置一列所合并的列数，例如

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=10",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "columns": [
                {
                    "name": "id",
                    "label": "ID"
                },

                {
                    "name": "browser",
                    "label": "Browser"
                },

                {
                    "name": "version",
                    "label": "Version"
                }
            ],
            "affixRow":[
                {
                    "type": "text",
                    "text": "总计",
                    "colSpan": 2
                },
                {
                    "type": "tpl",
                    "tpl": "${rows|pick:version|sum}"
                }
            ]
        }
    ]
}
```

上例中我们给 `总计` 列配置了 `"colSpan": 2`，它会合并两个单元格

### 配置多行

可以配置二维数组来配置多行总结行

```schema: scope="body"
{
    "type": "service",
    "api": "/api/mock2/sample?perPage=10",
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "columns": [
                {
                    "name": "browser",
                    "label": "Browser"
                },

                {
                    "name": "version",
                    "label": "Version"
                }
            ],
            "affixRow":[
                [
                    {
                        "type": "text",
                        "text": "总计1"
                    },
                    {
                        "type": "tpl",
                        "tpl": "${rows|pick:version|sum}"
                    }
                ],
                [
                    {
                        "type": "text",
                        "text": "总计2"
                    },
                    {
                        "type": "tpl",
                        "tpl": "${rows|pick:version|sum}"
                    }
                ]
            ]
        }
    ]
}
```

## 行操作按钮

通过 itemActions 可以设置鼠标移动到行上出现操作按钮

```schema: scope="body"
{
  "type": "service",
  "api": "/api/mock2/sample?perPage=10",
  "body": [{
    "type": "table",
    "source": "$rows",
    "itemActions": [{
      "label": "编辑",
      "type": "button",
      "actionType": "dialog",
      "dialog": {
        "title": "编辑",
        "body": "这是个简单的编辑弹框"
      }
    }, {
      "label": "删除",
      "type": "button",
      "actionType": "ajax",
      "confirmText": "确认要删除？",
      "api": "/api/mock2/form/saveForm"
    }],
    "columns": [{
        "name": "browser",
        "label": "Browser"
      },

      {
        "name": "version",
        "label": "Version"
      }
    ]
  }]
}
```

## 单行点击操作

> 1.4.0 及以上版本

处理前面的 itemActions，还可以配置 itemAction 来实现点击某一行后进行操作，支持 [action](./action) 里的所有配置，比如弹框、刷新其它组件等。

```schema: scope="body"
{
  "type": "service",
  "api": "/api/mock2/sample?perPage=10",
  "body": [{
    "type": "table",
    "source": "$rows",
    "itemAction": {
      "type": "button",
      "actionType": "dialog",
      "dialog": {
        "title": "详情",
        "body": "当前行的数据 browser: ${browser}, version: ${version}"
      }
    },
    "columns": [{
        "name": "browser",
        "label": "Browser"
      },
      {
        "name": "version",
        "label": "Version"
      }
    ]
  }]
}
```

注意这个属性和 `checkOnItemClick` 冲突，因为都是定义行的点击行为，开启 `itemAction` 后 `checkOnItemClick` 将会失效。

## 行角标

> 1.5.0 及以上版本

通过属性`itemBadge`，可以为表格行配置[角标](./badge)，可以使用[数据映射](../../../docs/concepts/data-mapping)为每一行添加特定的 Badge 属性。[`visibleOn`](../../../docs/concepts/expression)属性控制显示的条件，表达式中`this`可以取到行所在上下文的数据，比如行数据中有`badgeText`字段才显示角标，可以设置`"visibleOn": "this.badgeText"`

```schema: scope="body"
{
  "type": "service",
  "body": {
    "type": "table",
    "source": "${table}",
    "syncLocation": false,
    "itemBadge": {
      "text": "${badgeText}",
      "mode": "ribbon",
      "position": "top-left",
      "level": "${badgeLevel}",
      "visibleOn": "this.badgeText"
    },
    "columns": [
        {
            "name": "id",
            "label": "ID",
            "searchable": {
              "type": "input-text",
              "name": "id",
              "label": "主键",
              "placeholder": "输入id",
              "size": "sm",
            }
        },
        {
            "name": "engine",
            "label": "Rendering engine"
        },
        {
            "name": "browser",
            "label": "Browser",
            "searchable": {
              "type": "select",
              "name": "browser",
              "label": "浏览器",
              "placeholder": "选择浏览器",
              "size": "sm",
              "options": [
                {
                  "label": "Internet Explorer ",
                  "value": "ie"
                },
                {
                  "label": "AOL browser",
                  "value": "aol"
                },
                {
                  "label": "Firefox",
                  "value": "firefox"
                }
              ]
            }
        },
        {
            "name": "platform",
            "label": "Platform(s)"
        },
        {
            "name": "version",
            "label": "Engine version",
            "searchable": {
              "type": "input-number",
              "name": "version",
              "label": "版本号",
              "placeholder": "输入版本号",
              "size": "sm",
              "mode": "horizontal"
            }
        },
        {
            "name": "grade",
            "label": "CSS grade"
        }
    ]
  },
  data: {
    table: [
      {
        "id": 1,
        "engine": "Trident",
        "browser": "Internet Explorer 4.0",
        "platform": "Win 95+",
        "version": "4",
        "grade": "X",
        "badgeText": "默认",
        "badgeLevel": "info"
      },
      {
        "id": 2,
        "engine": "Trident",
        "browser": "Internet Explorer 5.0",

        "badgeText": "危险",
        "badgeLevel": "danger"
      },
      {
        "id": 3,
        "engine": "Trident",
        "browser": "Internet Explorer 5.5",
        "platform": "Win 95+",
        "version": "5.5",
        "grade": "A"
      },
      {
        "id": 4,
        "engine": "Trident",
        "browser": "Internet Explorer 6",
        "platform": "Win 98+",
        "version": "6",
        "grade": "A"
      },
      {
        "id": 5,
        "engine": "Trident",
        "browser": "Internet Explorer 7",
        "platform": "Win XP SP2+",
        "version": "7",
        "grade": "A"
      }
    ]
  }
}
```

## 表格内容高度自适应

> 1.5.0 及以上版本

通过 `autoFillHeight` 可以让表格内容区自适应高度，具体效果请看这个[示例](../../../examples/crud/auto-fill)。

它的展现效果是整个内容区域高度自适应，表格内容较多时在内容区域内出滚动条，这样顶部筛选和底部翻页的位置都是固定的。

开启这个配置后会自动关闭 `affixHeader` 功能避免冲突。
