基本排序

ng-table提供一个表头来增加基本的排序功能。

（1）指定具体哪一列需要排序

（2）可以通过<code>NgTableParams</code>可选择的提供初始列排序

（3）在这个例子中需要为<code>NgTableParams.sorting()</code>设置值，然后展示出来。

下面是代码：

<div ng-app="myApp" class="container-fluid">
  <div class="row">
    <div class="col-xs-12">
      <h2 class="page-header">Sorting - basic example</h2>
      <div class="row">
        <div class="col-md-6">
          <div class="bs-callout bs-callout-info">
            <h4>Overview</h4>
            <p><code>ngTable</code> provides a header template that adds sorting to a html table</p>
            <ul>
              <li>Specify which column should be sortable</li>
              <li>Optionally supply the initial columns to sort to the <code>NgTableParams</code> constructor call</li>
            </ul>
          </div>
        </div>
        <div class="col-md-6">
          <div class="bs-callout bs-callout-warning">
            <h4>Got a <code>getData</code> function?</h4>
            <p>In this case you'll need to apply the values from <code>NgTableParams.sorting()</code> to the data you want to display in your table. This is typically the case when the data is being fetched from the server.</p>
          </div>
        </div>
      </div>
    </div>
  </div>
  <div class="row">
    <div class="col-md-6" ng-controller="demoController as demo">
      <h3>ngTable directive</h3>
      <table ng-table="demo.tableParams" class="table table-condensed table-bordered table-striped">
        <tr ng-repeat="row in $data">
          <td data-title="'Name'" sortable="'name'">{{row.name}}</td>
          <td data-title="'Age'" sortable="'age'">{{row.age}}</td>
          <td data-title="'Money'">{{row.money}}</td>
        </tr>
      </table>
    </div>
    <div class="col-md-6" ng-controller="dynamicDemoController as demo">
      <h3>ngTableDynamic directive</h3>
      <table ng-table-dynamic="demo.tableParams with demo.cols" class="table table-condensed table-bordered table-striped">
        <tr ng-repeat="row in $data">
          <td ng-repeat="col in $columns">{{row[col.field]}}</td>
        </tr>
      </table>
    </div>
  </div>
</div>
