引导表上的滚动条

Question

我有table在panel内的modal内呈现。由于表格相对较大，我想将其限制为5行，以便模态不会变得可滚动。我查看了SO和google以及我看到的任何地方，我需要设置overflow-y:auto或overflow-y:scroll才能使其正常工作，但在我的情况下，它没有。我还设置了400px的随机高度和position：absolute。这使得表格可以滚动，但现在面板以<thead>关闭，表格的主体在面板外部呈现。解决这个问题的方法是什么？

我的代码段是：

<div class="modal fade">
   <div class="modal-dialog " >
      <div class="modal-content">
         <div class="modal-body">
            <div class="panel panel-default">
               <div class="panel-body">
                  <table class="table table-bordered>
                     <thead>
                         [........]
                     </thead>
                     <tbody style="overflow-y:auto; height:400px; position:absolute>
                     [.......]
                     </tbody>
                   </table>

[...... </div>的剩余部分......]

修改

感谢您的回复。有没有办法将滚动条缩小到仅<tbody>，以便<thead>保持静止？

Answer 1

将其包裹在table-responsive并设置最大高度：

.table-responsive {
    max-height:300px;
}

尝试一次我给你一个例子问题

＆＃13;

＆＃13;

table,tr,th,td{
  border:1px solid #dddddd;
  border-collapse:collapse;
}
.tbl-header{
  width:calc(100% - 17px);
  width:-webkit-calc(100% - 17px);
  width:-moz-calc(100% - 17px);
}

＆＃13;

<div class="tbl-header">
<table style="width:100%;">
  <thead>
<tr>
 <th width="50%">1</th>
  <th width="50%">2</th>
 </tr>
 </thead>
</table>
  </div>
<div style="width:100%;overflow:auto; max-height:100px;">
   <table style="width:100%;">
     <tr>
     <td width="50%">dsada</td>
       <td width="50%">dsadas</td>
     </tr>
     <tr>
     <td>dsada</td>
       <td>dsadas</td>
     </tr>
     <tr>
     <td>dsada</td>
       <td>dsadas</td>
     </tr>
     <tr>
     <td>dsada</td>
       <td>dsadas</td>
     </tr>
     <tr>
     <td>dsada</td>
       <td>dsadas</td>
     </tr>
     <tr>
     <td>dsada</td>
       <td>dsadas</td>
     </tr>
    
    </table>
   </div>
