相关热点：组件表格锁定 ROWHEADNUM element.rows for 风格 NAME

1、在页面中引入风格单定义
<style>
.LockHeadTable {behavior:url(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">
