矩阵类型的输入框。

## 基本用法

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "debug": true,
  "controls": [
    {
      "type": "matrix",
      "name": "matrix",
      "label": "Matrix",
      "rowLabel": "行标题说明",
      "columns": [
        {
          "label": "列1"
        },
        {
          "label": "列2"
        }
      ],
      "rows": [
        {
          "label": "行1"
        },
        {
          "label": "行2"
        }
      ]
    }
  ]
}
```

## 单选模式

配置`"multiple": false`可以设置单选，配置`singleSelectMode`可以设置单选模式

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "debug": true,
  "controls": [
    {
      "type": "matrix",
      "name": "matrix",
      "label": "Matrix",
      "rowLabel": "行标题说明",
      "multiple": false,
      "columns": [
        {
          "label": "列1"
        },
        {
          "label": "列2"
        }
      ],
      "rows": [
        {
          "label": "行1"
        },
        {
          "label": "行2"
        }
      ]
    }
  ]
}
```

## 动态选项

可以配置 source 渲染动态选项

```schema: scope="body"
{
  "type": "form",
  "api": "https://3xsw4ap8wah59.cfc-execute.bj.baidubce.com/api/amis-mock/mock2/form/saveForm",
  "controls": [
    {
        "name": "matrix",
        "type": "matrix",
        "label": "动态矩阵组件",
        "source": "/api/mock2/options/matrix?waitSeconds=1"
    }
  ]
}
```

以上面为例，source 接口返回格式如下：

```json
{
  "status": 0,
  "msg": "ok",
  "data": {
    "columns": [
      {
        "label": "Col A",
        "col": "a"
      },
      {
        "label": "Col B",
        "col": "b"
      },
      {
        "label": "Col C",
        "col": "c"
      },
      {
        "label": "Col D",
        "col": "d"
      },
      {
        "label": "Col E",
        "col": "e"
      }
    ],
    "rows": [
      {
        "label": "Row 1",
        "rol": 1
      },
      {
        "label": "Row 2",
        "rol": 2
      },
      {
        "label": "Row 3",
        "rol": 3
      },
      {
        "label": "Row 4",
        "rol": 4
      },
      {
        "label": "Row 5",
        "rol": 5
      },
      {
        "label": "Row 6",
        "rol": 6
      }
    ]
  }
}
```

### column 模式

默认为 column 模式，即每列只能单选某个单元格

```schema: scope="body"

        },
        {

        }
      ],
      "rows": [
        {

## 属性表

除了支持 [普通表单项属性表](./formitem#%E5%B1%9E%E6%80%A7%E8%A1%A8) 中的配置以外，还支持下面一些配置

| 属性名           | 类型                           | 默认值     | 说明                                                                                                                                                        |
