如果固定高度的列标题是可以接受的,那么这个问题可以用纯 CSS 来解决。
这是一个配置了可变表宽度和自动列宽度的示例,就像 OP 的表一样:jsFiddle
请注意,在该示例中,垂直滚动条仅在必要时出现,因此您可能需要调整框架大小才能看到它。
下面的代码与小提琴相同,但具有固定的桌子高度。只要有足够的行数超过指定的高度,滚动条就会始终显示在该配置中:

<div>

<thead>
<tr>
<th><div label="Column 1"/></th>
<th><div label="Column 2"/></th>
<th><div label="Column 3"/></th>

<!--more versatile way of doing column label; requires 2 identical copies of label-->
<div><div>Column 4</div><div>Column 4</div></div>
</th>
<th class="scrollbarhead"/> <!--ALWAYS ADD THIS EXTRA CELL AT END OF HEADER ROW-->

必须更改背景颜色并移除边框,使其看起来与 OP 的表格完全相同。可以在 CSS 注释中找到进行这些类型更改的说明。
