    这部分讲解ui-grid的排序功能,排序功能是默认存在的,可以在ui-grid设置enableSorting标识符来设置 enable/disable。<p>
    /需要注意的是:需要引入<code>ngAnimate</code>模块。/
    (1)通过设置enableSorting: false在列上禁止排序。

    (2)多列也能够被排序,比如点击了gender然后点击name

    (3)点击菜单排序,这个排序效果是叠加性质的。比如你点击量一个按钮排序,在点击另外一个按钮排序,这个效果是叠加性质的,而不是取代。

    (4)当点击头部的时候,会移除所有的排序。

    (5)当编辑数据的时候表格排序是自己重新计算的。当在后台更改数据的时候,需要重新计算的时候,需要调用<code> gridApi.core.notifyDataChange( uiGridConstants.dataChange.EDIT )</code>来进行通知。

    (6)可以通过为列设置<code> suppressRemoveSort: true</code>来设置默认的排序。

    (7)点击一个列表的头部,排序先是向上,然后向下,最后是没有排序效果。

    (8)排序算法是基于列表类型的,ui-grid能够自动猜测这个数据类型。但是还可以显示的设置列表类型,让其自动计算。

    (9)可以通过<code> sortingAlgorithm</code>自定义排序算法。

     <div ng-controller="MainCtrl">
     Click on a column header to sort by that column. (The third column has sorting disabled.)
     To demonstrate the live sorting we provide a button that toggles the gender of Alexander Foley.
     Sort by gender (ASC - so click twice) then name (using shift click), so that Alexander is at the top of the grid,
     then click the toggleGender button.
     
     <br>
     <br>
     <button id='toggleGender' ng-click='toggleGender()' class="btn btn-success" >Toggle Gender</button>
     <div id="grid1" ui-grid="gridOptions1" class="grid"></div>
     
     <br>
     You can set an initial sort state for the grid by defining the `sort` property on your column definitions.
     The `direction` sub-property says which way to sort, and the `priority` says what order to sort the columns
     in (lower priority gets sorted first).
