HTML Tables In ASP

I have a form in my HTML page and I require a number of checkboxes. These are to be dynamically generated from an Access database. The code below will work but it will only create a single row. How can I include the <TR> tag inside the loop - I'd probably want 4 cells per row

<table>
<tr>
<%

Do until rstCategories.EOF = True

Response.Write "<TD width=200>"_
& rstCategories("strCategory")_
& "<input name=chkCategory type=checkbox value=" &rstCategories("lngID")>"_
& "</TD>"

rstCategories.Movenext
Loop
%>
</tr></table>
