我问了三天都没人能解答的问题
<!--#include   file=conn.asp-->  
<%  
sq= "select   top   12   *   from   ad   where   gy_true <> 0 "  
set   rs=server.createobject( "adodb.recordset ")  
rs.open   sq,conn,1,1  
%>  


<div   align= "center ">  
<table   width= "100% "   height= "100 ">  
<%if   i   mod   6=0   then%>  
<tr>  
<%end   if%>  
<%do   while   not   rs.eof%>  
<td   align=center   width=160   height=50> nothing   to   say </td>  
</td>  
<%if   i   mod   5   =0   then%>  
</tr>  
<%end   if%>  
<%  
rs.movenext  
i=i+1  
loop  
%>  
</table>  
</div>  

首先我这代码是有错误的,只有i   mod   6=0时才存在 <tr> 其他时候不存在   我想实现的是   当一行达到6列就换行

------解决方案--------------------
改了一下，你参考
<div align= "center ">
<table width= "100% " height= "100 " border= "1 ">
<%
dim i
i=0
do while not rs.eof%>
<tr>
<%do while i <6 and not rs.eof%>
<td> <%=rs( "num ")%> </td>
<%rs.movenext
i=i+1%>
<%loop%>
</tr>
<%
i=0
loop%>
</table>
</div>
