### 🧐 问题描述

`ProDescriptions`中`valueType`为`textarea`时编辑模式的`input`大小不正确，编辑模式下的``组件能够正确接受`rows`参数作，但是当设置`width: 100%`的时候，由于外层包裹了无长度的`div`，造成样式无变化。此外，使用`renderFormItem`进行自定义也是一样的。

### 💻 示例代码

现有的`columns`中对应字段的定义
```
{
label: '个人简介',
dataIndex: 'introduction',
valueType: 'textarea',
span: 2,
fieldProps: {
rows: 10,
style: {
minWidth: '100%',
width: '100%',
},
},
}
```

Start by reproducing the ProDescriptions edit-mode case with valueType set to textarea, rows set to 10, and the supplied width and minWidth styles. Compare the behavior with a renderFormItem customization as described. Done means the textarea's rendered input size responds correctly to the column and fieldProps sizing in both cases.
