formating output

I'm sure this is easy and I'll feel silly when I see how it's done, but, my mnd is a blank, this structure prints out a table with a new row for each item <table > <? While ( $results = mysql_fetch_array($pointer)) { print "<tr><td ><$results[1] </td></tr>" ; } ?> </table> what I want to do is print out a table 4 columns wide and however many rows high needed to run through the data HOW do I loop through the array and get <td>data</td> printed 4 times then a new row started and then 4 more <td> cells printed, etc thank you in advance
