把这个JS加到你的项目中·····

var pltsPop=null;
var pltsoffsetX = 10; // 弹出窗口位于鼠标左侧或者右侧的距离；3-12 合适
var pltsoffsetY = 15; // 弹出窗口位于鼠标下方的距离；3-12 合适
var pltsPopbg="#FFFFEE"; //背景色
var pltsPopfg="#111111"; //前景色
var pltsTitle="";
document.write('<div id=pltsTipLayer style="display: none;position: absolute; z-index:10001"></div>');
function pltsinits()
{
document.onmouseover = plts;
document.onmousemove = moveToMouseLoc;
}
function plts()
{ var o=event.srcElement;
if(o.alt!=null && o.alt!=""){o.dypop=o.alt;o.alt=""};
if(o.title!=null && o.title!=""){o.dypop=o.title;o.title=""};
pltsPop=o.dypop;
if(pltsPop!=null&&pltsPop!=""&typeof(pltsPop)!="undefined")
{
pltsTipLayer.style.left=-1000;
pltsTipLayer.style.display='';
var Msg=pltsPop.replace(/\n/g,"<br>");
Msg=Msg.replace(/\0x13/g,"<br>");
var re=/\{(.[^\{]*)\}/ig;
if(!re.test(Msg))pltsTitle="<font color=#ffffff>中国移动校讯通欢迎您！</font>";
else{
re=/\{(.[^\{]*)\}(.*)/ig;
pltsTitle=Msg.replace(re,"$1")+" ";
re=/\{(.[^\{]*)\}/ig;
Msg=Msg.replace(re,"");
Msg=Msg.replace("<br>","");}
var attr=(document.location.toString().toLowerCase().indexOf("list.asp")>0?"nowrap":"");
var content =

moveToMouseLoc();
return true;
}
else
{

return true;
}
}

function moveToMouseLoc()
{
if(pltsTipLayer.innerHTML=='')return true;
var MouseX=event.x;
var MouseY=event.y;
//window.status=event.y;
var popHeight=pltsTipLayer.clientHeight;
var popWidth=pltsTipLayer.clientWidth;
if(MouseY+pltsoffsetY+popHeight>document.body.clientHeight)
{
popTopAdjust=-popHeight-pltsoffsetY*1.5;
pltsPoptop.style.display="none";
pltsPopbot.style.display="";
}
else
{
popTopAdjust=0;
pltsPoptop.style.display="";
pltsPopbot.style.display="none";
}
if(MouseX+pltsoffsetX+popWidth>document.body.clientWidth)
{
popLeftAdjust=-popWidth-pltsoffsetX*2;
topleft.style.display="none";
botleft.style.display="none";
topright.style.display="";
botright.style.display="";
}
else
{
popLeftAdjust=0;
topleft.style.display="";
botleft.style.display="";
topright.style.display="none";
botright.style.display="none";
}
pltsTipLayer.style.left=MouseX+pltsoffsetX+document.body.scrollLeft+popLeftAdjust;
pltsTipLayer.style.top=MouseY+pltsoffsetY+document.body.scrollTop+popTopAdjust;
return true;
}
pltsinits();

然后在引用的页面上加上样式，当然你也可以写在CSS里面哈····

<style>
.tableBorder7{width:800;solid; background-color: #000000;}
TD{font-family: 宋体;font-size: 12px;line-height : 15px ;}
th{background-color: #f7f7f7;color: #000000;font-size: 12px;font-weight:bold;}
th.th1{background-color: #333333;}
td.TableBody7{background-color: #B1EA45;}
</style>

搞定·····
