Question

我试图制作一个（响应的）Bootstrap表。向下滚动表数据时，我希望表头滚动。我不希望为表格设置高度，因为当添加更多行时，我希望页面增加。因此，仅设置高度和overflow-y: scroll是不够的。

设置position: fixed甚至position: sticky也不能解决我的问题。

这是我尝试过的code：

.example {
  padding: 5px;
  margin: 5px 0;
  border-radius: 2px;
  background-color: #afc8f0;
  text-align: center;
}

thead {
  /* position: fixed; */
}

Bootstrap是否提供任何支持这种功能（固定/粘性表格标题）的东西？

Answer 1

我在here之前已经回答了这个问题。您可以通过设置position: sticky;

来做到这一点

table thead tr th {
  background-color: white;
  position: sticky;
  top: -1px;
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<table class="table">
  <thead>
    <tr>
      <th>column1</th>
      <th>column2</th>
      <th>column3</th>
      <th>column4</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
    <tr>
      <td>td</td>
      <td>td</td>
      <td>td</td>
      <td>td</td>
    </tr>
  </tbody>

</table>

Answer 2

只需将其添加到您的CSS中：

table thead tr:first-child th {
  position: sticky;
  top: 0px;
  background-color: #afc8f0;
}

Answer 3

根据Mohd Tabish Baig的评论，我发现显然我必须对目标元素进行更深入的研究。我没有将var query2 = connection.query('UPDATE campaigns SET USED=0 where amount=?' , [amount], function (error, results, fields) { console.log(query2.sql); if (error) throw error; // Get here all updated rows }添加到select name, artist AND texte from testsearch near texte where to_tsvector(texte) @@ to_tsquery('randomname');，而是不得不将其更具体地添加到其子position: sticky中。下面的小提琴展示了一个可以帮助我的解决方案：

thead

th
