Question

我有200行的表。第一行有标题（th标签）。当我向下滚动时，标题将被固定并且对所有行都可见。有什么帮助吗？

谢谢

最简单的回答，看看这个 - ＆gt; http://www.imaputz.com/cssStuff/bigFourVersion.html

一个警告：对IE 7-9不起作用（适用于6和10）。如果您需要7-9的解决方案，请尝试jQuery Scrollable Table Plugin。您甚至可以通过在IE if comments内放置javascript调用来将其设置为仅使用JS for IE版本7-9。然后你就会知道任何使用更好的浏览器的人都会使用纯CSS（更快）而且你有一个使用垃圾的解决方案...我的意思是IE 7,8或9。

它基本上与CSS有关。一个关键是将table-body设置为display: block。另一个问题是处理固定宽度。看看吧。复制这个例子真的很容易。

我说的真的不多！这个例子是PURE CSS，没有JS！
