那段addRow方法是用select   标签onchange方法调用的 
每次调用这个方法的时候都是继续增加行和列 
但我的本意是为每个select选项单独增加几行或者几列 
请问各位大大怎么解决噢吖~

    但我的本意是为每个select选项单独增加几行或者几列   
    这句什么意思?
      

  2.   

    就以上面的例子来说
    当b=1的时候，我加了一行两列，如存栏量和出栏量
    当b=2的时候，上面增加的那行我不想要，只想增加另外一行或者多行，而不是在增加的基础上继续增加噢~
    用delete方法或者写多个页面都好麻烦的，请问有什么办法解决啊？

    如果只是确定的增加一行可以行得通，但如何某个条件增加若干行呢？

  6.   

    把i改成addRowCount,不好意思打錯了
      

  7.   

    你把row1 = tb.insertRow()放在if語句裡不就可以不產生多餘的Row了嗎,這樣也可以少Delete幾行
