1、在页面中引入风格单定义

<style>

.lockheadtable {behavior:url(/oblog312/lockheadtable.htc)}

</style>

2、在需要锁定行列头的表格定义中添加语句“class=lockheadtable”就ok了，其他参数有

rowheadnum=锁定行数

colheadnum=锁定列数

rowheadstyle=行表头风格

colheadstyle=列表头风格

rowstyle=行风格1|行风格2|……|行风格n

focusstyle=获得鼠标焦点时的风格

3、点击行标题时可以对数据进行排序

注意：

使用本组件时，行表头中的单元格不允许跨行

例：

<table class=lockheadtable rowheadnum=3 colheadnum=1 rowheadstyle=background:#f7f7f7; color:black; colheadstyle=background:#f7f7f7; color:black; rowstyle=background:#ffffff; color:black;|background:#f7f7f7; color:black; focusstyle=background:green; color:white; width=1500 border=1 cellpadding=3 cellspacing=0 align=center>
