DataTables ordering选项

DataTables是jQuery插件，可用于为网页的HTML表格添加互动和高级控件。这也使得表中的数据可以根据用户的需要进行搜索、排序和过滤。DataTable还暴露了一个强大的API，可以进一步用来修改数据的显示方式。

排序选项用于指定是否启用DataTable中数据的排序。DataTable中的记录可以根据用户选择的行以升序或降序排列。一个真值可以启用这种排序，一个假值可以禁用它。

语法:

{ ordering: value }

选项值：该选项有一个上面提到的和下面描述的单一价值。

value。这是一个布尔值，指定是否启用DataTable中的数据排序。默认值是true。

下面的例子说明了这个选项的使用。

示例1：本示例禁用了DataTable的排序功能。
