html - 使用CSS选择器在嵌套表中选择tr中的所有td

Question

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 - 简短版

我知道有未关闭的标签，但我从我的调试器中复制了它，因为所有内容都是由 jquery 生成的。有什么想法吗？

   <table class="wc-header">
    <thead>
        <tbody>
            <tr>
                <td rowspan="3">Medewerker 1</td>
                <td class="row_header">Van</td>

编辑

也许我应该解释一下我实际上想做什么。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，但边框会被 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;
}

已解决

我遇到了 td 的覆盖问题。在我发布问题后意识到这一点，感谢帮助

提前致谢

使用

tbody tr:first-child td {/* your styles */}
