我在包装器里面有一个表。当用户滚动时，我需要列标题在顶部是静态的。我有那部分工作正常。
其他要求之一是可以显示或隐藏列，并且标题应该调整。这似乎与一个小错误有关：当用户滚动然后点击＆＃34;隐藏列＆＃34;时，标题文本正在消失。

答案 0 :(得分：1)
它在我的IE中没有问题，但Chrome有你提到的问题
我试图在thead中添加一个类，其位置为：absolute，它可以正常工作
.head {
position: absolute;
}
并将其添加到thead中的tr
<thead>
<tr class="head">
<th>Col 1</th>
<th>Col 2</th>
<th>Col 3</th>
<th>Col 4</th>
<th>Col 1</th>
<th>Col 2</th>
<th>Col 3</th>
<th>Col 4</th>
<th>Col 1</th>
<th>Col 2</th>
<th>Col 3</th>
<th>Col 4</th>
<th>Col 1</th>
<th>Col 2</th>
<th>Col 3</th>
<th>Col 4</th>
