    </div><!-- /fixed-table-container -->
  </div><!-- /container --> 
  
  
  </html>

 

第2种方法：

在包含table的页面添加以下css即可

table thead {
  display:table;
  width: 100%;
  background-color: lightblue;
  position: fixed;
}
table{
  table-layout:fixed;
}

方法3在包含table的页面添加以下css即可(目前最好的方案)

table {
  text-align: left;
  position: relative;
  border-collapse: collapse; 
  }
 
 
   thead th {
     text-align: center;
   }
  th {
   
  position: sticky;
  background-color: #fff;
  top: 0; /* Don't forget this, required for the stickiness */
   
  }

固定列请参考 https://blog.p2hp.com/archives/7680
注意：position: sticky 发现当 sticky 元素（祖先）容器使用了 overflow: hidden 时，sticky 就失效了。
