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

最简单的解决方法是添加 pointer-events: none ::after 和 ::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。
