A design I was working on used titles above an image in the feature area. The height of the titles needed to be consistent so they would line up.
This is is a trick for iterating cells as a unit so the titles are in a cell above an image. Complicated algorithms are avoided. In this example, the content is stored in two arrays: $tittles and $products.
$c=0;
$cc=0;
$total=count($products);
for ($c =0; $c <= $total; $c=$c+4) {
echo
"<tr>".
"<th>".$titles[$c]."</th>\n".
"<th>".$titles[$c+1]."</th>\n".
"<th>".$titles[$c+2]."</th>\n".
"<th>".$titles[$c+3]."</th>\n".
"</tr>";
echo
"\n\n".
"<tr class='image_row'>\n".
"<td>".$products[$cc]."</td>\n".
"<td>".$products[$cc+1]."</td>\n".
"<td>".$products[$cc+2]."</td>\n".
"<td>".$products[$cc+3]."</td>".
"</tr>\n";
$cc=$cc+4;
}
