非JavaScript高手不可：如何实现网页的分割条？
一个三行的表格如下：
<table width="100%" border="0"> <tr> <td> </td> </tr> <tr> <td> </td> </tr> <tr> <td> </td> </tr></table>
<TITLE> 分隔条 </TITLE><script language="javascript"><!--//------------------------------------// CopyRight (c) 宝玉 2006//------------------------------------var oSplitter, oTdSplitter, oTdTop, oTdBot, oTable;var posTdSplitter, posTable;var bLoaded = false;var bStart = false;var iPadding = 0;function Position(x, y){ this.x = x; this.y = y;}function GetPosition(obj){ var objThis = obj; var oBody = document.body; var oLeft = oTop = 0; while (objThis!=oBody) { oLeft += objThis.offsetLeft; oTop += objThis.offsetTop; objThis = objThis.offsetParent; } return new Position(oLeft, oTop); }function fnInit(){ oSplitter = document.getElementById("splitter"); oTdSplitter = document.getElementById("tdSplitter"); oTdTop = document.getElementById("tdTop"); oTdBot = document.getElementById("tdBot"); oTable = document.getElementById("table"); posTable = GetPosition(oTable); oSplitter.style.height = oTdSplitter.offsetHeight; oSplitter.style.width = oTdSplitter.offsetWidth; bLoaded = true;}function fnMouseDown(event){ if (bLoaded == false) { alert("页面加载未完成，请稍候！"); return; } posTdSplitter = GetPosition(oTdSplitter); iPadding = posTdSplitter.y - event.clientY; oSplitter.style.top = posTdSplitter.y; oSplitter.style.left = posTdSplitter.x; oSplitter.style.display = "block"; if (oSplitter.setCapture) oSplitter.setCapture(); bStart = true;}function fnMouseUp(event){ if (bStart == true) { oSplitter.style.display = "none"; if (event.clientY > posTable.y && event.clientY < posTable.y + oTable.offsetHeight - oTdSplitter.offsetHeight) { oTdTop.style.height = event.clientY - posTable.y; } if (oSplitter.releaseCapture) oSplitter.releaseCapture(); bStart = false; }}function fnMouseMove(event){ if (bStart == true) { oSplitter.style.top = event.clientY + iPadding; }}//--></script></HEAD><body onload="fnInit();" onmouseup="fnMouseUp(event);" onmousemove="fnMouseMove(event);" style="margin:0px;" onselectstart="return false;"><div style="position: absolute;width:4px;height:400px;background-color: black;z-index:9999;display:none;cursor: col-resize;" id="splitter"></div><table cellspacing="0" cellpadding="0" border="0" style="height:100%; width:100%;" id="table"> <tr> <td id="tdTop" > </td> </tr> <tr> <td style="height: 8px; overflow:hidden;cursor: col-resize;border-top:1px solid black;border-bottom:1px solid black;" id="tdSplitter" onmousedown="fnMouseDown(event);"> </td> </tr> <tr> <td id="tdBot" > </td> </tr></table></body></HTML>

怎么搞的？
删掉了条语句。
