各位大虾会的就帮帮忙，在线等
在表格中原先有一行，动态添加的行中td的样式不起作用，是什么问题？
代码如下

else
{
var weight = parseInt(document .all["tb_line"+i].value);
if(weight<=100 && weight >0)
{
WeightT += parseInt(document .all["tb_line"+i].value);
}
else
{
alert ("权重必须是0到100之间的数字！");
}
}
}
document .all["lb_weight"].innerHTML = WeightT ;
};
function delTR(obj)
{
var table = obj .parentNode.parentNode.parentNode;
table .removeChild(obj .parentNode.parentNode);
};
function Add_tr()
{

{

}

trobj .setAttribute ("id","tr"+linenum);
// 添加td0
