javascript - 如何折叠所有表格行

Question

我在一个表中有表行，每行内还有另一个嵌套表行，我的问题是我可以在嵌套表行中折叠和展开，但是当我尝试在主表中展开时，只有第一行被展开当我启动程序时，默认情况下会扩展其余的，我该如何修复它。

这是我的代码

tbody.collapse.in {
  display: table-row-group;
}

.tigray {
  background-color: darkcyan;
}

.zoba {
  background-color: forestgreen;
}

您不能在另一个 tbody 中使用 tbody
it is not legal HTML.

  <tbody id="group-of-rows-3" class="collapse">
      <tr class="table-warning">
        <td>nested title4</td>
        <td>13</td>
        <td>13</td>
      </tr>
      <tr class="table-warning">
        <td>nested title5</td>
        <td>18</td>
        <td>13</td>

        <td>32</td>

      </tr>
    </tbody>
</table>

但是，您可以在单个 TABLE 元素中包含多个 TBODY 元素，因此您可以这样做:

<table> 
  <tbody> 
    <tr> 
      <td>...</td> 
      <td>...</td> 
    </tr> 
  </tbody>
  <tbody > 
    <tr> 
      <td>...</td> 
      <td>...</td> 
    </tr> 
  </tbody>
  <tbody> 
    <tr> 
      <td>...</td> 
      <td>...</td> 
    </tr> 
  </tbody>
</table>
