我试图做固定的滚动标题。在这个过程中，试图将 HEAD 表的位置固定固定。我做的。但是，当我滚动表格时， HEAD 表格正在闪烁。它在 Firefox 中不闪烁。我不想在 IE、Chrome 或任何浏览器中出现这种闪烁。任何帮助将不胜感激。
代码：
<style type="text/css">
th {
background:#663300;
color:#FFF;}
</style>
查询代码
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>

$(document).ready(function() {
$("#mainDiv").scroll(function() {
var offSet = $("#mainDiv").offset().top;
$("#headTable").offset({"top":offSet});
});
});
