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">
