我想选择 tbody 的第一个 tr 内的所有 td 。我通常会这样做： tbody:first-child td --> 但这给了我你可以在图像上看到的结果，黄色是结果。
我的 html - 短版
我知道有未关闭的标签，但我从调试器中复制了它，因为一切都是由 jquery 生成的。有任何想法吗？

也许我应该解释一下我实际上想要做什么。您在左侧看到的黑线是给 TBODY 的边框。我希望这条线具有表格的宽度，但边框被 td 的边框覆盖。也许还有其他解决方案？
CSS
[data-person] {
border:1px solid #DEDEDE;
}
tbody tr:first-child td {
background-color:yellow;
}
解决了
我对 td 有一个覆盖问题。在我发布我的问题后意识到这一点，谢谢帮助
提前致谢
