Question

我需要使用datatable来添加排序，分页和搜索我在本例中创建的表。但是，我无法让它发挥作用。我花了很多时间来减轻类型错误而没有运气。每当我尝试添加数据表时，都会收到此错误：

“未捕获的TypeError：无法读取未定义的属性'长度'”

请提出解决方案。我已经使用了Bootstrap表和dynatable。我需要数据表来解决我的直播dom排序问题。

这是我的代码：

我确保在从我的研究中导入dataTable之前，我只使用过一次jQuery。

您需要在第一行创建列或删除它：

<table  class="table table-bordered table-hover" id="tab_logic" ">
        <thead>
          <tr >
            <th class="text-center">
              #
            </th>
            <th class="text-center">
              Name
            </th>
            <th class="text-center">
              Mail
            </th>
            <th class="text-center">
              Mobile
            </th>
          </tr>
        </thead>
        <tbody>
        <tr id='addr0'>
          <td></td>
          <td></td>
          <td></td>
          <td></td>
        </tr>
        </tbody>
      </table>

如何使dataTable.js在这个例子中工作（动态jQuery表）？
