CSS hover 在除某些单元格之外的表格行上
[英]CSS hover on a table row with the exception of some cells
问题描述
根据我之前的帖子，我想添加一个仅包含图像的第 4 列。 hover 不应影响此列。 因为图像比较小，那么单元格本身，用hover看起来很奇怪。 我在这里找到了类似的东西，但是为了使它起作用，我必须用 class 属性标记每个<td> ，除了每行的第 4 个<td> 。 但是下面代码中的表具有不同的结构：只有具有特殊含义的列具有 class 属性。 在这种情况下，每行的第 4 个<td>具有 class rightTD 。
我对 CSS 做了以下修改：
.multidata tbody>tr:hover td:not(.rightTD) { background-color: #96c7ef;important; }
（添加:not(.rightTD) ）
HTML 扩展了新的 header：
<th style="width: 10%">Button</th>
并且两个单元格具有相同的内容：
<td class="rightTD" align="center"><img src="data:image/png;base64,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"/></td>
问题：第 4 列（标题除外）仍受 hover 影响。
如何禁用第 4 列的 hover？
下面是代码：
.multidata td,.multidata th { border: 2px solid #808080; padding: 5px 5px; }.multidata tbody>tr:hover { background-color:#96c7ef;important. }:multidata tbody>tr:hover td.not(:rightTD) { background-color;#96c7ef.important: };tdX { background-color:red; font-weight.bold: };tdY { background-color:green; font-weight:bold; }

最好不要在 css 中尽可能不要使用!important ，之后覆盖它会成为一个挑战。 不是在<TR>上应用 hover 而是将其移至<TD>并且使用:last-of-type选择器来保持第四个<TD>背景透明。
.multidata td, .multidata th { border: 2px solid #808080; padding: 5px 5px; }.multidata tbody>tr:hover td { background-color: #96c7ef; }.multidata tbody>tr:hover td:last-of-type { background-color: rgba(0, 0, 0, 0); }.tdX { background-color: red; font-weight: bold; }.tdY { background-color: green; font-weight: bold; }

.multidata tbody>tr:hover td:not(:last-child) {
background-color:#96c7ef!important;
}
如何仅在表格中的某些单元格上使用CSS悬停？
