jquery - 如何在一页上有 2 个固定标题？

coder 2023-08-10 原文

我有一个带有固定页眉的页面，在该页下方有一个表格，我希望有一个固定的表格标题，因此当我滚动时，我总是看到页眉，然后是下面的表格标题。当我尝试修复 thead 时，这搞砸了 thead 的列对齐。我该如何纠正这个问题？

编辑:我的问题是如何让列标题与列对齐？

编辑:另请注意，我需要两个标题...一个在页面顶部，另一个用于表格。

如果我没看错的话..我为你制作了一个演示 http://jsfiddle.net/aV54L/
没有 jQuery，没有 JavaScript .. 只有 CSS

代码如下:

<!DOCTYPE HTML>

    z-index:5;
}
.col1{

    border: 1px solid #000;
}
.col2{
    width: 20%;
    border: 1px solid #000;

.col3{
    width: 25%;
    border: 1px solid #000;
}
.col4{
    width: 15%;
    border: 1px solid #000;
}

#tableHeader {
