  1.   

    <tr onMouseOver="this.bgColor='#999999'" onMouseOut="this.style.backgroundColor=''">
    就是这一句，先后试过：
    <tr onMouseOver="this.style.backgroundColor='#999999'" onMouseOut="this.style.backgroundColor=''">
    都不行
      

  2.   

    把tr里的td的背景色去掉就是<td bgcolor="#FFFFFF" align="center">&nbsp;张三&nbsp;</td>--->>><td align="center">&nbsp;张三&nbsp;</td>
      

  3.   

    另外：onMouseOver="this.bgColor='#999999'" onMouseOut="this.style.backgroundColor=''"要改成
    onMouseOver="this.bgColor='#999999'" onMouseOut="this.bgColor=''"或：
    onMouseOver="this.style.backgroundColor='#999999'" onMouseOut="this.style.backgroundColor=''"
