关于固定表头和列，加改变列宽的问题，高难度！！！！

我在一个表格中采用Div+CSS方式固定了表头和列，但我的改变表格列宽功能动不对了。请问各们高手可有解决方法，如果能有其它办法也行，但必须是对同一个Table操作，高分相送，谢谢!代码如下：
<锁定表头及列的样式>
.LockHeader
{
position: relative;
top: expression(this.offsetParent.scrollTop);
z-index:10;
}

.LockColumn
{
position: relative;
left: expression(this.parentElement.offsetParent.parentElement.scrollLeft);
}
对于改变列宽的代码太长，贴最重要的吧。(参考网上做的)
sub elementOnMouseMove
'鼠标移动事件：
dim cliX, cliY
if iDragCounter < 10 then
iDragCounter = iDragCounter + 1
exit sub
end if
if (bDragMode and not objDragItem is nothing) then '当前为拖动模式
with window.event
cliX = .clientX
cliY = .clientY
.cancelBubble = false
.returnValue = false
end with
with objDragItem
if (.style.visibility = "hidden") then .style.visibility = "visible"
.style.posLeft = cliX - (.offsetWidth / 2)
.style.posTop = cliY - (.offsetHeight - 3)
end with
dragHeadHitIndex = hitTest(cliX, cliY)
end if
end sub

sub elementHeadOnMouseUp
'第一行操作：调整列宽，鼠标抬起:调整列宽
If CurDownMode=True Then '调整表格宽度
'抬起鼠标：调整位置，取消状态
Dim CurTable
Set CurTable=element
