我们可以通过document.getElementById('tb').childNodes[0]获得tbody对象，
然后通过tbody.length进行遍历，如tbody.chilNode[i].
也可以直接获得rows数组遍历，如document.getELementById('tb').rows.
对于行我们可以通过sectionRowIndex和rowIndex获得位置.
rowIndex:
Retrieves the position of the object in the rows collection for the table.
sectionRowIndex:
Retrieves the position of the object in the tBody, tHead, tFoot, or rows collection.
代码如：
[code]
function a(par) {
var trow=document.getElementById(par).rows;
var l=trow.length;
for(var i=0;i<l;i++) {
if(trow[i].rowIndex%2==0)
trow[i].style.backgroundColor="#F2F2F2";
else
trow[i].style.backgroundColor="#ffffff"
}
}
[/code]
