columnsToggle

起始版本号: Buttons 1.0.0

一组按钮切换单个列的可见性

注意：这个需要使用Bottons扩展

说明(Description)

这是一组按钮，自动生成相同标题的文本列，可以用来切换列的可见性

The columnsToggleButton button type differs from the colvisButton type in that it does not extend the collectionButton type (although it could be assigned to a collection's buttons attribute if you wished). The buttons for each column are automatically expanded where this button is included.

选项(Options)

这个按钮有以下选项配置:

名称	默认
`columns`	undefined
Columns selector that defines the columns to include in the column visibility button set. By default this is `undefinedType` which results in all columns being selected, but any of the `column-selectorType` options can be used to define a custom button set.
`visibility`	undefined
用来给选中的列设置值，`true`为显示， `false`为隐藏， `undefined`为切换当前状态

示例

Datatables初始化：显示每一列的按钮

$('#myTable').DataTable( {
    buttons: [ 'columnsToggle' ]
} );

Datatables初始化：只显示class名为toggle的按钮

$('#myTable').DataTable( {
    buttons: [ {
        extend: 'columnsToggle',
        columns: '.toggle'
    } ]
} );

直接初始化：在集合中显示每一列的按钮，和 colvis按钮是一样的

new $.fn.dataTable.Buttons( table, {
    buttons: [
        {
            extend: 'collection',
            buttons: [ 'columnsToggle' ]
        }
    ]
} );
