我有一个通过foreach(PHP)生成的表问题是我想修改这个表上的一些特定单元格(红色)知道我不能添加一个类，我必须用CSS样式访问它
编辑:
我需要为第一个和最后一个添加样式 <td> , 最后一个<tr>与 .child类
确实，这是一个创建 <tr> 的 ajax 请求与 .child类 所以有时有 2 <tr>有时 10 <tr>
.tb-child .child th, .tb-child .child td, .details-close {
background: #f3f3f3;
text-align: center;
}
tbody > tr.child:last-child > td:first-child {
border-radius: 4px
}

</div>我尝试了几种方法，例如:
tbody > tr.child:last-child > td:first-child {
border-radius: 4px
}
但是没有任何效果..怎么办？
最佳答案
这对你有用。
我使用了 nth-last-child(2) 来定位红色的 td。
我添加的代码:
tbody > tr:nth-last-child(2)>td:first-child,tbody > tr:nth-last-child(2)>td:last-child {
border-radius: 4px;
}
.tb-child .child th, .tb-child .child td, .details-close {
background: #f3f3f3;
text-align: center;
}
tbody > tr:nth-last-child(2)>td:first-child,tbody > tr:nth-last-child(2)>td:last-child {
border-radius: 4px;

</div>但是有些样式来自bootstarap css，所以如果你想过度调整它们，你也必须在你的样式中使用!important。
示例 -
tbody > tr:nth-last-child(2)>td:first-child,tbody > tr:nth-last-child(2)>td:last-child {
border-radius: 4px !important;
}
希望这对您有所帮助。
