增加的新列为什么里面的表格颜色不能和第一行一样？
1.增加的新列为什么里面的表格颜色不能和第一行一样目的是让增加的第二列也把第一列的背景色带过来，增加和第一行完全一样
2.搞了好长时间都弄不好，关键是对代码不熟悉，只靠自己猜，请高手指点
<form action=" " name="form1 ">
<input onclick= "deleteRow() " name="Submit " value="删除 " type="text" /> <input maxlength="4" size="4" name="num " value="1 " type="text" /> <input onclick= "insertRow() " name="Submit2 " value="增加 " type="text" /> <br />
