看源码的疑惑。。。
在看一个论坛的源码，
发贴和回帖它是分别用的两个DataList，
这个是显示发帖内容的前台代码：
<asp:datalist   id= "DataList_Q "   runat= "server "   Width= "100% "   CellPadding= "0 ">
<ItemTemplate>
<TABLE   cellSpacing=1   cellPadding=0   width= "100% "   bgColor=#a0bce7   border=0>
<TR>
<TD   bgColor=#ffffff>
<TABLE   cellSpacing=0   cellPadding=4   width= "100% "   align=center   border=0>
<TR   class=a3>
<TD   colSpan=2>
<TABLE   cellSpacing=0   cellPadding=0   width= "100% "   border=0>
