我正在尝试在表头下面添加滚动条！这段代码适用于滚动，但我试图保持表格标题和标题的固定。我尝试在<tbody>标记之前添加预滚动类，并在css中添加tbody {column-count: 10;}，但不起作用。我不确定，但可能是因为只有1个<tr>？任何帮助都将不胜感激。感谢
<div class="container">
<div class="row pre-scrollable">
<div class="panel panel-default">
<div class="panel-heading">

<table class="table table-fixed table-hover table-striped" align="center">

<tr>
<th class="col-xs-2 col-lg-2 col-md-2 col-sm-2">Publication Date</th>
<th class="col-xs-6 col-lg-8 col-md-8 col-sm-8">Article</th>
<th colspan="2" class="col-xs-2 col-lg-2 col-md-2 col-sm-2">Action</th>

首先在下面的div中添加表：
<div id="table-wrapper">
<div id="table-scroll">
<table>
..... // all table content
</table>
</div>
</div>
应用此css：
#table-wrapper {
position:relative;
}
#table-scroll {
height:150px;
overflow:auto;
margin-top:20px;
}
#table-wrapper table {
width:100%;
}
#table-wrapper table * {
background:yellow;
color:black;
}
