🧐[问题]請問SchemaForm跟ProForm設了Group,如何一行只顯示一個Field?

### 🧐 问题描述
設定Group後，我不管怎麼調整底下Field的寬度，一行就是顯示兩個Field，有辦法調成一行只顯示一個Field嗎?
或是有其他類似Group的組件能做到能折疊的功能又一行只顯示一個Field?

### 💻 示例代码
```
{
title: '分组1',
valueType: 'group',
fieldProps: {
collapsible: true,
style: {
backgroundColor: '#f0f7ff'
},
titleStyle: {
backgroundColor: '#7ebaff'
}
},
columns: [
{
title: '标签',
dataIndex: 'labels',
width: 'xl',
},
{
title: '创建时间',
key: 'showTime',
dataIndex: 'createName',
valueType: 'date',
width: 'xl',
}
],
},
```

### 🚑 其他信息


Start by reading the SchemaForm and ProForm entry points for the valueType: 'group' configuration, focusing on how the supplied columns are laid out and how collapsible fieldProps are handled. Reproduce the provided example and determine whether the existing configuration supports one field per row; done means documenting or implementing a clear way to keep the group collapsible while displaying one field per row.
