### 🧐 问题描述

### 💻 示例代码
```ts
// 搜索表单
const search: ProTableProps['search'] = {
span: 6,
labelWidth: 0,
collapsed,
showHiddenNum: false,
optionRender: false,
collapseRender: false,
onCollapse: refreshScrollY,
};
```

### 🚑 其他信息

Start at the ProTable search implementation and trace how span, collapsed, optionRender, collapseRender, and showHiddenNum affect the number of visible search controls. Reproduce the provided configuration and screenshot, then verify that the collapsed state displays the expected four controls.
