我一直在尝试冻结我的第一行,但最终我只得到了“Test3”标题。
我使用position: fixed;under table th {},但没有运气。
有什么建议么?

您修复的所有<th>标签都堆叠在一起。将固定应用于<tr>您想要修复的。

此外,如果<tr>您要修复的顶部是列的标题,它们应该在<thead>. 那么你的其他<tr>s 应该在 a 中<tbody>。这也将允许您在 CSS 中使用thead tr.

甚至更好,只需修复<thead>整个thead {position: fixed}

我不确定你的问题,但似乎你想创建一个用 scroll 固定的标题,另一个选项是将你所有的内容包装在一个 div 上并申请所有这些。

表头固定的其他示例: codepen.io/tjvantoll/pen/JEKIu
