Table表格拖动，既可以拖动行，也可以拖动列。代码如下：

Html代码

<html>
<head>
<style>
.resizeDivClass
{
position:relative;
width:4;
z-index:1;
left:expression(this.parentElement.offsetWidth - 3);
cursor:e-resize;
}
.resizeDivClass2
{
position:relative;
width:expression(this.parentElement.offsetWidth);
height:1px;
border: solid 0px;
z-index:1;
top:expression(this.parentElement.offsetHeight - 5);
cursor:n-resize;
}
</style>
<script language=javascript>
function MouseDownToResize(obj)
{
obj.mouseDownX=event.clientX;
objobj.pareneTdW=obj.parentElement.offsetWidth;
obj.pareneTableW=theObjTable.offsetWidth;
obj.setCapture();
}
function MouseMoveToResize(obj)
{
if(!obj.mouseDownX)
{
return false;
}
var newWidth=obj.pareneTdW*1+event.clientX*1-obj.mouseDownX;
if(newWidth>0)
{
obj.parentElement.style.width = newWidth;
theObjTable.style.width=obj.pareneTableW*1+event.clientX*1-obj.mouseDownX;
}
}
function MouseUpToResize(obj)
{
obj.releaseCapture();
obj.mouseDownX=0;
}
function MouseDownToResize2(obj)
{
obj.mouseDownY = event.clientY;
obj.pareneTrH = obj.parentElement.offsetHeight;
obj.pareneTableH=theObjTable.offsetHeight;
obj.setCapture();
}
function MouseMoveToResize2(obj)
{
if(!obj.mouseDownY)
{
return false;
}
var newWidth = obj.pareneTrH * 1 + event.clientY * 1 - obj.mouseDownY;
if(newWidth > 0)
{
obj.parentElement.style.height = newWidth;
theObjTable.style.height = obj.pareneTableH * 1 + event.clientY * 1 - obj.mouseDownY;
}
}
function MouseUpToResize2(obj)
{
obj.releaseCapture();
obj.mouseDownY=0;
}
</script>
</head>
<body>
