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">
源代码：
LockHeadTable.htc(组件程序)
<PUBLIC:COMPONENT>
<PUBLIC:PROPERTY NAME="ROWHEADNUM" />
<PUBLIC:PROPERTY NAME="COLHEADNUM" />
<PUBLIC:PROPERTY NAME="ROWHEADSTYLE" />
<PUBLIC:PROPERTY NAME="COLHEADSTYLE" />
<PUBLIC:PROPERTY NAME="ROWSTYLE" />
<PUBLIC:PROPERTY NAME="FOCUSSTYLE" />
<script>
//初始化
ROWHEADNUM = (ROWHEADNUM==null?0:parseInt(ROWHEADNUM, 10));
COLHEADNUM = (COLHEADNUM==null?0:parseInt(COLHEADNUM, 10));
ROWHEADSTYLE = (ROWHEADSTYLE==null?"":ROWHEADSTYLE);
COLHEADSTYLE = (COLHEADSTYLE==null?"":COLHEADSTYLE);
arrRowStyle = (ROWSTYLE==null?new Array(""):ROWSTYLE.split("|"));
//设置行表头
var i, j, rowItem, cellItem;
rowHead = element.cloneNode(true);
for (i=0; i<ROWHEADNUM; i++) {
rowItem = element.rows(i);
rowItem.style.cssText = 'z-index:10; position:relative; top:expression(this.offsetParent.scrollTop);' + ROWHEADSTYLE;
}
//设置列表头
for (i=0; i<element.rows.length; i++) {
rowItem = element.rows(i);
if (i>=ROWHEADNUM) {
rowItem.style.cssText = "position:relative;" + arrRowStyle[(i - ROWHEADNUM) % arrRowStyle.length];
if (FOCUSSTYLE!=null) {
rowItem.onmouseover = function () { this.style.cssText = "position:relative;" + FOCUSSTYLE;}
