hi,
simplest way would be to loop through the results and store them in an array, then loop through that whilst outputting the table:
eg:
$res = mysql_query($yourquery);
$resarray = array();
while( $resarray[] = mysql_fetch_assoc($res));
for( $i = 0; $i < 150; $i++){
echo '<tr><td>'.$resarray[$i]['field'].'</td>'
echo '<td>'.$resarray[$i+150]['field'].'</td></tr>'
}
would that work for you?
