我正在使用CSS转换创建一个固定高度的可滚动表格,顶部有一个固定的标题。
该技术效果很好,除非某些表内容具有CSS position: relative
,在这种情况下,内容显示在标题的前面而不是后面。我尝试过设置z-index
,但这没有用。
我已经在线搜索了一下,我知道这与他们有单独的堆叠上下文有关,但我无法弄清楚如何让它工作。
以下示例代码。查看第一列滚动标题而不是后面。
更新:经过进一步测试后,似乎z-index
确实在Firefox中有效,但在Chrome中无效。
$(function () {
$('#container').bind('scroll', (event) => {
$('#table thead').css('transform', `translate(0, ${event.target.scrollTop}px)`);
});
});

#container {
max-height: 300px;
overflow: auto;
}
table {
width: 100%;
border-collapse: collapse;
}
thead {
z-index: 1;
background-color: grey;
}
td:first-child {
position: relative; /* this *needs* to be relative */
}
