#### 筛选和排序
对某一列数据进行筛选,使用列的 `filters` 属性来指定需要筛选菜单的列,`onFilter` 用于筛选当前数据,`filterMultiple` 用于指定多选和单选。
对某一列数据进行排序,通过指定列的 `sorter` 函数即可启动排序按钮。`sorter: function(rowA, rowB) { ... }`, rowA、rowB 为比较的两个行数据。
使用 `defaultSortOrder` 属性,设置列的默认排序顺序。
#### Filter and sorter
Use `filters` to generate filter menu in columns, `onFilter` to determine filtered result, and `filterMultiple` to indicate whether it's multiple or single selection.
Use `sorter` to make a column sortable. `sorter` can be a function of the type `function(a, b) { ... }` for sorting data locally.
Uses `defaultSortOrder` to make a column sorted by default.
If a `sortOrder` or `defaultSortOrder` is specified with the value `ascend` or `descend`, you can access this value from within the function passed to the `sorter` as explained above. Such a function can take the form: `function(a, b, sortOrder) { ... }`.
