When I need to do something like this I always use this base code that
I just edit. I wrote it a few years ago and haven't really changed it
so it works for what I need.
<?php
$results = 17; // how many cells do we actually have data for? [put
your record count here]
$cols = 8; // desired column width of the table
$total = $cols * ceil($results / $cols); // total cells to create
$rows = ceil($total / $cols); // total rows to create
$position = 0; // current position
echo "<br>results: ", $results;
echo "<br>cols: ", $cols;
echo "<br>total: ", $total;
?>
<table border="1">
<?php for ($row=0; $row < $rows; ++$row): ?>
<tr>
<?php for ($col=0; $col < $cols; ++$col): ?>
<?php if ($results > $position): ?>
<td>
<?php
// call your fetch record code here
echo 'Col: '. $col .'<br>';
echo 'Row: '. $row .'<br>';
echo 'Position: '. $position .'<br>';
?>
</td>
<?php else: ?>
<td>
empty cell
</td>
<?php endif; ?>
<?php ++$position; ?>
<?php endfor; ?>
</tr>
<?php endfor; ?>
</table>
