CSS高亮表格行列无效

我有 4 个并排的 table ,就像 Highlight column and row in a table ::after and ::before not work 中的那个一样

我的问题是,以该问题中的表格为例,当鼠标从 c 移动到 b 或 a(或从 b 移动到 a)时,突出显示停留在 c 所在的行,而不是移动到 b 或 a (与 b) 保持一致。基本上,当鼠标从上到下移动时效果很好,但从下到上移动时效果不佳。

我想知道如何解决它。因为我也让表格单元格在点击时高亮显示,并记录哪个单元格高亮和不高亮,所以问题有时会在点击时高亮错误的单元格,从而导致记录有偏差。

我正在使用 Chrome 进行测试。

举个例子

            th{
font-weight: normal;
align-content: center;
}
td {
border: black solid;
border-width: 1px 2px 1px 1px;
padding: 5px;
text-align: center;
height:1.1cm;
width:1.1cm;
background-clip: padding-box

}
.col {
width: 1.1cm;
}
.rotate {
text-align: center;
white-space: nowrap;
vertical-align: middle;
width: 1.5em;
}
.rotate div {
-moz-transform: rotate(-90.0deg); /* FF3.5+ */
-o-transform: rotate(-90.0deg); /* Opera 10.5 */
-webkit-transform: rotate(-90.0deg); /* Saf3.1+, Chrome */
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083)"; /* IE8 */

margin-right: -1cm;

最佳答案

最简单的解决方法是添加 pointer-events: none ::after::before 伪元素。 It also has a great browser support .

老实说,我还没有看过代码 xD,但可能另一个修复方法是乱用 z-index,我不推荐,因为它可以用 解决指针事件

            th{
font-weight: normal;
align-content: center;
}
td {
border: black solid;
border-width: 1px 2px 1px 1px;
padding: 5px;
text-align: center;
height:1.1cm;
width:1.1cm;
background-clip: padding-box

}
.col {
width: 1.1cm;
}
.rotate {
text-align: center;
white-space: nowrap;
vertical-align: middle;
width: 1.5em;
}
.rotate div {
-moz-transform: rotate(-90.0deg); /* FF3.5+ */
-o-transform: rotate(-90.0deg); /* Opera 10.5 */
-webkit-transform: rotate(-90.0deg); /* Saf3.1+, Chrome */
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=0.083)"; /* IE8 */
margin-left: -1cm;
margin-right: -1cm;
}

width: 25%;
float: left;
