#### template 风格的 API
|
|
使用 template 风格的 API
|
|
“Last Name” 列展示了列筛选在 template 风格 API 中的通常用法。
|
|
“Tags” 列展示了自定义列筛选以及“双向绑定”的 filterDropdownVisible 属性，其内部使用了事件 update:filterDropdownVisible。
|
|
> 这个只是一个描述 `columns` 的语法糖，所以你不能用其他组件去包裹 `Column` 和 `ColumnGroup`。

#### template style API
|
|
Using template style API
|
|
The "Last Name" column shows the normal usage of column filter using template style API.
|
|
The "Tags" column shows a customized column search, and also the "two-way binding" of prop filterDropdownVisible, which use event update:filterDropdownVisible.
|
|
> Since this is just a syntax sugar for the prop `columns`, so that you can't compose `Column` and `ColumnGroup` with other Components.
