you could do this with Divs and spans. add the repeat region around the span tag:
example:
<div style="width:600px; overflow:hidden;">
<?php do { ?>
<span style="float:left;width:200px;"><?php echo $_rowRecordsetName['columnName']</span>
<?php } while ($row_recordsetName = mysql_fetch_assoc($recordsetName)); ?>
</div>
