javascript - 在 TH 中按类排序表

Question

我有一个包含 10 列的表，每一列都有不同的类，例如最后一列有:data-tot

如何按类降序排列表格？

一个完整的jsFiddle is available here ，但 HTML 的一小部分看起来像这样(odd 和 even 行继续用于完整数据)。

<table class="sp-league-table sp-data-table sp-sortable-table sp-scrollable-table sp-paginated-table dataTable no-footer" data-sp-rows="30" id="DataTables_Table_9" role="grid">
  <thead>
    <tr role="row">
      <th class="data-rank sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="Pos">Pos</th>
      <th class="data-name sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="Squadra">Squadra</th>
      <th class="data-gia sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="GIA">GIA</th>
      <th class="data-ros sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="ROS">ROS</th>
      <th class="data-gio sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="6GIO">6GIO</th>
      <th class="data-giotwo sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="5GIO">5GIO</th>
      <th class="data-giothree sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="4GIO">4GIO</th>
      <th class="data-giofour sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="3GIO">3GIO</th>
      <th class="data-tav sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="TAV">TAV</th>
      <th class="data-tot sorting" tabindex="0" aria-controls="DataTables_Table_9" rowspan="1" colspan="1" aria-label="TOT">TOT</th>
    </tr>
  </thead>
  <tbody>
    <tr class="odd" role="row">
      <td class="data-rank">1</td>
      <td class="data-name"><a href="http://www.quartuleague.com/squadra/consulenza-impresa/">CONSULENZA IMPRESA</a></td>
      <td class="data-gia">0.5</td>
      <td class="data-ros">0</td>
      <td class="data-gio">0.5</td>
      <td class="data-giotwo">1</td>
      <td class="data-giothree">0</td>
      <td class="data-giofour">0</td>
      <td class="data-tav">0</td>
      <td class="data-tot">2.0</td>
    </tr>
    <tr class="even" role="row">
      <td class="data-rank">2</td>
      <td class="data-name"><a href="http://www.quartuleague.com/squadra/new-team/">NEW TEAM</a></td>
      <td class="data-gia">0.5</td>
      <td class="data-ros">2</td>
      <td class="data-gio">1.0</td>
      <td class="data-giotwo">1</td>
      <td class="data-giothree">0</td>
      <td class="data-giofour">0</td>
      <td class="data-tav">0</td>
      <td class="data-tot">4.5</td>
    </tr>
  </tbody>
</table>

SOLUTION

使用下面的代码按 jQuery 选择器 .data-tot 指定的列对表格进行降序排序。

$('#myTable').DataTable().column('.data-tot').order('desc').draw();

参见 columns().order()了解更多详情。
