当水平和垂直滚动条可用时修复表格标题

Question

我想修改html表头。我在表格中有很多列，因此需要垂直滚动条来滚动并查看列数据。我想修复表格标题，以便当用户向下滚动以查看行时，标题是固定的。 请查阅演示http://jsfiddle.net/ZcLSE/1425/。 当用户向下滚动表头时，应该是固定的，对用户可见。请咨询。

CSS代码：

.modal-body { 
overflow-y: auto; 
} 
tbody { 
} 
thead, tbody tr { 
} 
thead { 
    width: calc(100% - 1em) 
} 
table {border-collapse:collapse; height:300px;overflow: auto; 
    display: block;} 
table td {border:solid 1px #fab; width:100px; word-wrap:break-word;} 

HTML代码：

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal"> 
    Launch demo modal 
</button> 

<div id="myModal" class="modal fade"> 
    <div class="modal-dialog"> 
     <div class="modal-content"> 
      <div class="modal-header"> 
       <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button> 
       <h4 class="modal-title">Modal title</h4> 
      </div> 
      <div class="modal-body" id="modal-body"> 
       <table class="table" border="1">

     </div> 
     <!-- /.modal-content --> 
    </div> 
    <!-- /.modal-dialog --> 
</div> 
<!-- /.modal --> 

PS：需要垂直和水平滚动条，表中的标题应该是固定的。

我试过解决小提琴问题，我相信我遇到了和你一样的问题，thead变得比容器更大。

我会推荐这个JQuery Plugin这是专门为您的需要。
