html - 增加 Bootstrap 4 表格的列宽

Question

我需要增加列宽，我试过 width-%,PX,rem 但这不起作用。
如果表格的列数较少，我可以增加列宽，但在我的场景中，如果我的列数超过 15 列，则无法更改宽度。

<div class="table-responsive">
<table class="table">
  <thead>
    <tr>

<th scope="col">#</th><th scope="col">#</th>

      <th scope="col" style="width: 500px;">Heading heading'</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>
    </tr>
  </thead>
  <tbody>
    <tr>

 <th scope="row">1</th><th scope="row">1</th>

      <td style="width: 300px;">jksdfn jhs fjidsh fj id hidsfdsfd</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>
    </tr>
   <tr>

 <th scope="row">1</th><th scope="row">1</th>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>

      <td>Cell</td><td>Cell</td>
    </tr>
  </tbody>
</table>

我需要增加下表中的第三列，附图供引用。

我用过 Always Responsive Bootstrap 4 Table

您需要使用 min-width而不是 width .
