I'm not sure exactly what you're looking for but using the "frame" & "rules" attributes along with specifying "colgroups" may help, see :
http://www.w3.org/TR/1999/REC-html401-19991224/struct/tables.html#h-11.3.1
http://www.w3.org/TR/1999/REC-html401-19991224/struct/tables.html#edef-COLGROUP

To remove the border of the input boxes, either use an inline style, or specify it in a CSS file.

<table frame=vsides rules=groups cellspacing=0 >
<colgroup>
<colgroup>
<thead>Header 1</thead><thead>Header 2</thead>
<tr><td><input type=text style="border:0"></td><td><input type=text style="border:0"></td></tr>
<tr><td><input type=text style="border:0"></td><td><input type=text style="border:0"></td></tr>
<tr><td><input type=text style="border:0"></td><td><input type=text style="border:0"></td></tr>
