🧐[问题]ProTable toolbar没有small模式

### 🧐 问题描述

ProTable defaultSize="small"，但是上面的toolbar仍然很高，看了下padding=16，怎么让toolbar变窄或者跟随small模式。

### 💻 示例代码
```

}}
defaultSize="small"
rowSelection={{
selectedRowKeys: selectedKeys,
onChange: setSelectedKeys,
}}
```

### 🚑 其他信息

Start by tracing ProTable's toolbar rendering and how the defaultSize="small" prop is applied to the table and toolbar. Verify the behavior with the provided toolbar and row-selection example; done means the toolbar height or padding follows the small mode.
