DataTables 不支持像您使用它们那样的 colspan.改用他们的复杂标题示例.

当使用表格显示数据时，您通常希望显示分组中的列信息.DataTables 完全支持 colspan 和标题中的行跨度，将所需的排序侦听器分配给适用于该列的 TH 元素.每列必须有一个 TH单元格(并且只有一个)对于听众来说是独一无二的 下面的例子有核心浏览器信息组合在一起.

When using tables to display data, you will often wish to display column information in groups. DataTables fully supports colspan and rowspans in the header, assigning the required sorting listeners to the TH element suitable for that column. Each column must have one TH cell (and only one) which is unique to it for the listeners to be added. The example shown below has the core browser information grouped together.

<thead>
    <tr>
        <th rowspan="2">Rendering engine</th>
        <th rowspan="2">Browser</th>
        <th colspan="3">Details</th>
    </tr>
    <tr>
        <th>Platform(s)</th>
        <th>Engine version</th>
        <th>CSS grade</th>
    </tr>
</thead>

你的等价物看起来像这样:

Your equivalent would look something like this:

<thead>
  <tr>    
    <th rowspan="2">&nbsp;</th> <!-- column 1 -->

    <th colspan="2">&nbsp;</th> <!-- column 2&3 -->
    <th colspan="2">&nbsp;</th> <!-- column 4&5 -->
  </tr>
 <tr>
    <th>&nbsp;</th> <!-- column 2 -->
    <th>&nbsp;</th> <!-- column 3 -->

    <th>&nbsp;</th> <!-- column 4 -->
    <th>&nbsp;</th> <!-- column 5 -->
 </tr>
</thead>
