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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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
{
    "$schema": "https://houtai.baidu.com/v2/schemas/table.json#",
    "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"
                    },

            }
        }
    ]
}
```

### 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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "width": "50%"
        }
    ]
}
```

### 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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "popOver": {
                "body": {
                    "type": "tpl",
                    "tpl": "${engine}"
                }
            }
        }
    ]
}
```

可以结合 truncate 用来优化表格中的长内容展示，比如默认只展示 20 个字符，剩下的点击查看更多出现。

```schema: scope="body"
{
    "type": "crud",
    "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID"
        },
        {
            "type": "tpl",
            "name": "engine",
            "label": "Rendering engine",
            "tpl": "${engine|truncate:2}",
            "popOver": {
                "trigger": "hover",
                "position": "left-top",
                "showIcon": false,
                "body": {
                    "type": "tpl",
                    "tpl": "${engine}"
                }
            }
        }
    ]
}
```

> 示例内容没那么长，直接配置成 2 个字符了。

可以给列上配置`popOverEnableOn`属性，该属性为[表达式](../../docs/concepts/expression)，通过[表达式](../../docs/concepts/expression)配置当前行是否启动`popOver`功能

```schema: scope="body"
{
    "type": "crud",
    "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/sample?waitSeconds=1",
    "columns": [
        {
            "name": "id",
            "label": "ID",
            "popOver": {
                "body": {
                    "type": "tpl",
                    "tpl": "${id}"
                }
            },
            "popOverEnableOn": "this.id == 1"
        },
        {
            "name": "engine",
            "label": "Rendering engine",
            "popOver": {
                "body": {
                    "type": "tpl",
                    "tpl": "${engine}"
                }
            }
        }
    ]
}
```

`popOver` 配置详情：

- `mode` 可配置成 `popOver`、`dialog` 或者 `drawer`。 默认为 `popOver`。
- `size` 当配置成 `dialog` 或者 `drawer` 的时候有用。
- `position` 配置弹出位置，只有 `popOver` 模式有用。
  可选参数：

  - `center`

  - `left-top`
  - `right-top`
  - `left-bottom`
  - `right-bottom`

  atX-atY-myX-myY
  即：对齐目标的位置-对齐自己的位置

  - `left-top-right-bottom` 在目标位置的左上角显示。
  - `left-center-right-center` 在目标的左侧显示，垂直对齐。
  - ...

  固定位置

  - `fixed-center`
  - `fixed-left-top`
  - `fixed-right-top`
  - `fixed-left-bottom`
  - `fixed-right-bottom`。

- `offset` 默认 `{top: 0, left: 0}`，如果要来一定的偏移请设置这个。
- `trigger` 触发弹出的条件。可配置为 `click` 或者 `hover`。默认为 `click`。
- `showIcon` 是否显示图标。默认会有个放大形状的图标出现在列里面。如果配置成 false，则触发事件出现在列上就会触发弹出。
- `title` 弹出框的标题。
- `body` 弹出框的内容。

### 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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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+",

                "grade": "C",
                "id": 2,
                "children": [
                {
                    "engine": "Trident",
                    "browser": "Internet Explorer 4.0",
                    "platform": "Win 95+",
                    "version": "4",
                    "grade": "X",
                    "id": 2001

                    "platform": "Win 95+",
                    "version": "5",
                    "grade": "C",

                }
                ]
            },
            {

                ]
            },

                    "label": "Grade"
                },

                }
            ]
        }
    ]
}
```

## 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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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。

```schema: scope="body"
{
    "type": "service",
    "data": {
        "rows": [
            {
                "engine": "Trident",
                "browser": "Internet Explorer 4.2",
                "platform": "Win 95+",
                "version": "4",
                "grade": "A"
            },
            {
                "engine": "Trident",
                "browser": "Internet Explorer 4.2",
                "platform": "Win 95+",
                "version": "4",
                "grade": "B"
            },
            {
                "engine": "Trident",
                "browser": "AOL browser (AOL desktop)",
                "platform": "Win 95+",
                "version": "4",
                "grade": "C"
            },
            {
                "engine": "Trident",
                "browser": "AOL browser (AOL desktop)",
                "platform": "Win 98",
                "version": "3",
                "grade": "A"
            },
            {
                "engine": "Trident",
                "browser": "AOL browser (AOL desktop)",
                "platform": "Win 98",
                "version": "4",
                "grade": "A"
            },
            {
                "engine": "Gecko",
                "browser": "Firefox 1.0",
                "platform": "Win 98+ / OSX.2+",
                "version": "4",
                "grade": "A"
            },
            {
                "engine": "Gecko",
                "browser": "Firefox 1.0",
                "platform": "Win 98+ / OSX.2+",
                "version": "5",
                "grade": "A"
            },
            {
                "engine": "Gecko",
                "browser": "Firefox 2.0",
                "platform": "Win 98+ / OSX.2+",
                "version": "5",
                "grade": "B"
            },
            {
                "engine": "Gecko",
                "browser": "Firefox 2.0",
                "platform": "Win 98+ / OSX.2+",
                "version": "5",
                "grade": "C"
            },
            {
                "engine": "Gecko",
                "browser": "Firefox 2.0",
                "platform": "Win 98+ / OSX.2+",
                "version": "5",
                "grade": "D"
            }
        ]
    },
    "body": [
        {
            "type": "table",
            "source": "$rows",
            "className": "m-b-none",
            "combineNum": 3,
            "columnsTogglable": false,
            "columns": [
                {
                    "name": "engine",
                    "label": "Rendering engine"
                },
                {
                    "name": "browser",
                    "label": "Browser"
                },
                {
                    "name": "platform",
                    "label": "Platform(s)"
                },
                {
                    "name": "version",
                    "label": "Engine version"
                },
                {
                    "name": "grade",
                    "label": "CSS grade"
                }
            ]
        }
    ]
}
```

## 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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/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}"
                    }
                ]
            ]
        }
    ]
}
```
