我的网页上有一个响应表。该表包含三列和很多行。但是,有些行的colspan 3仅包含一列。
我只需要一个带有两列其他表格的表格(仅适用于大屏幕),因此我需要将colspan修改为5。

无法在CSS中修改colspan,并且无法在JavaScript中从CSS获得@media查询。我不想在代码的两个地方都定义断点。另外,在JavaScript中,由于滚动条和浏览器对此的不同实现,存在正确识别屏幕宽度的问题(它可能不与CSS断点对应,请在此处阅读更多内容)。
是否有可能仅通过CSS断点实现此目标?我需要先将设计移动。
如果您从您的移动边界table到您的tdS,你可以用一个常数5为您列跨度。它不会创建多余的列。
对CSS的更改:
table {
border-spacing: 0;
border-collapse: collapse;
}
table td {
border: 1px solid white;

由于您要保持colspan= 3或5,因此可以使用媒体查询来做到这一点:
更新的HTML:
<td colspan="3">colspan=3</td>
<td colspan="5">colspan=5</td>
