当行内的单元格具有类名时，为什么 CSS 悬停在表格行上不起作用?

Why doesn#39;t CSS hover work on table rows when the cells inside the rows have class names?(当行内的单元格具有类名时，为什么 CSS 悬停在表格行上不起作用?)

问题描述

我被这个问题困住了，所以任何帮助都将不胜感激.我有一个有几行的表.行中的每个单元格都属于某个类.我使用这些类名为单元格着色.

I am stuck with this problem so any help would be appreciated. I have a table with several rows. Each cell within the row belongs to a certain class. I use these class names to colour the cells.

这是我表中的一个示例行:

Here is one example row from my table:

<tr>
     <td class = "summarypage-odd-column">Theme</td>    <td class = "summarypage-odd-column">Q2 2009</td>   <td class = "summarypage-odd-column">Q1 2009</td>
     <td class = "summarypage-even-column">Theme</td>   <td class = "summarypage-even-column">Q2 2009</td>  <td class = "summarypage-even-column">Q1 2009</td>
     <td class = "summarypage-odd-column">Business Area</td>    <td class = "summarypage-odd-column">Q1 2009</td>   <td class = "summarypage-odd-column">Q1 2008</td>
 </tr>

当用户将鼠标指针移到该行中的任何单元格上时，我想突出显示每一行.所以我使用下面的 CSS 代码来实现.

I would like to highlight each row when the user moves mouse pointer over any cell in that row. So I used the following CSS code to achieve that.

tr:hover {
  background-color: #FFFAF0; color: #000;
}

不幸的是，似乎因为每个表格数据单元格都有一个类名，悬停不起作用.但是如果我从数据单元格中删除类名，悬停就可以了.

unfortunately it seems because each table data cell has a class name, the hover does not work. But if I remove the class names from data cells, the hover works.

我的问题是有什么方法可以让悬停的东西适用于表格行，同时仍然具有行内表格数据单元格的类名.

My question is is there any way I can get the hover thing working for the table row, while still having class names for the table data cells inside the row.

推荐答案

试试这个:

tr:hover td {
  background-color: #FFFAF0; color: #000;
}

将其放在现有的 td 样式声明之后以确保安全

Place this after the existing td style declarations to be safe
