## zh-CN

通过 `filterDropdown` 自定义的列筛选功能，并实现一个搜索列的示例。

给函数 `clearFilters` 添加 `boolean` 类型参数 `closeDropdown`，是否关闭筛选菜单，默认为 `true`。添加 `boolean` 类型参数 `confirm`，清除筛选时是否提交已选项，默认 `true`。

## en-US

Implement a customized column search example via `filterDropdown`.

Add the `boolean` type parameter `closeDropdown` to the function `clearFilters`. Whether to close the filter menu is `true` by default. Add the `boolean` type parameter `confirm` to clear whether to submit the option during filtering. The default is `true`.
