可拖动单元格的JavaScript示例
<html>
<head>
<title>拖动行测试</title>
<script language="javascript">
var beginMoving=false;
function MouseDownToMove(obj){
obj.style.zIndex=1;
obj.mouseDownY=event.clientY;
obj.mouseDownX=event.clientX;
beginMoving=true;
obj.setCapture();
}

function MouseMoveToMove(obj){
if(!beginMoving) return false;
obj.style.top = (event.clientY-obj.mouseDownY);
obj.style.left = (event.clientX-obj.mouseDownX);
}

function MouseUpToMove(obj){
if(!beginMoving) return false;
obj.releaseCapture();
obj.style.top=0;
obj.style.left=0;
obj.style.zIndex=0;
beginMoving=false;
var tempTop=event.clientY-obj.mouseDownY;
var tempRowIndex=(tempTop-tempTop%25)/25;
if(tempRowIndex+obj.rowIndex <0 )tempRowIndex=-1;
else tempRowIndex=tempRowIndex+obj.rowIndex;
if(tempRowIndex >= obj.parentElement.rows.length-1) tempRowIndex = obj.parentElement.rows.length-1;
obj.parentElement.moveRow(obj.rowIndex,tempRowIndex);
}
