我该如何制作带粘性桌面的Bootstrap表？

Question

我正在尝试制作一个（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，仅设置高度并overflow-y: scroll不够的。

设置position: fixed或均匀position: sticky也不会解决我的问题。

这是我尝试的代码 ：

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

 <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" /> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.7/umd/popper.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script> <div class="container"> <div class="row"> <div class="col"> <div class="example"> ... Example ... </div> <div class="example"> ... Example ... </div> <div class="example"> ... Example ... </div> <!-- ... Some other elements .. --> <table class="table table-striped table-hover table-sm"> <thead> <tr> <th scope="col">#</th> <th scope="col">First</th> <th scope="col">Last</th> <th scope="col">Handle</th> </tr> </thead> <tbody> <tr> <th scope="row">1</th> <td>Mark</td> <td>Otto</td> <td>@mdo</td> </tr> <tr> <th scope="row">2</th> <td>Jacob</td> <td>Thornton</td> <td>@fat</td> </tr> <tr> <th scope="row">3</th> <td>Larry</td> <td>the Bird</td> <td>@twitter</td> </tr> <tr> <th scope="row">1</th> <td>Mark</td> <td>Otto</td> <td>@mdo</td> </tr> <tr> <th scope="row">2</th> <td>Jacob</td> <td>Thornton</td> <td>@fat</td> </tr> <tr> <th scope="row">3</th> <td>Larry</td> <td>the Bird</td> <td>@twitter</td> </tr> <tr> <th scope="row">1</th> <td>Mark</td> <td>Otto</td> <td>@mdo</td> </tr> <tr> <th scope="row">2</th> <td>Jacob</td> <td>Thornton</td> <td>@fat</td> </tr> <tr> <th scope="row">3</th> <td>Larry</td> <td>the Bird</td> <td>@twitter</td> </tr> <tr> <th scope="row">1</th> <td>Mark</td> <td>Otto</td> <td>@mdo</td> </tr> <tr> <th scope="row">2</th> <td>Jacob</td> <td>Thornton</td> <td>@fat</td> </tr> <tr> <th scope="row">3</th> <td>Larry</td> <td>the Bird</td> <td>@twitter</td> </tr> <tr> <th scope="row">1</th> <td>Mark</td> <td>Otto</td> <td>@mdo</td> </tr> <tr> <th scope="row">2</th> <td>Jacob</td> <td>Thornton</td> <td>@fat</td> </tr> <tr> <th scope="row">3</th> <td>Larry</td> <td>the Bird</td> <td>@twitter</td> </tr> </tbody> </table> <div class="example"> ... Example ... </div> <div class="example"> ... Example ... </div> <div class="example"> ... Example ... </div> <!-- ... Some other elements .. --> </div> </div> </div> 

Bootstrap没有提供任何支持这种功能（固定/粘性表格标题）的东西吗？

Answer 1

在此之前，我已经回答了这个问题 。 您可以通过设置position: sticky;来实现此目的position: sticky;

 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：

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。 与其添加position: sticky对thead ， thead将其更具体地添加到其子th 。 以下小提琴显示了一个对我有所帮助的解决方案：

 .example { padding: 5px; margin: 5px 0; border-radius: 2px; background-color: #afc8f0; text-align: center; } table thead tr th { position: sticky; top: 0px; background: #fff; }
