php - Modifying Column Spans based on Item count -

-

ho can modify columns can add in colspan if needed based on number of items in row?

scenarios:

say have 5 items, need 1 row/4 columns, next row 1 column colspan="4"

say have 6 items, need 1 row/4 columns, next row, 2 columns colspan="2"

say have 7 items, need 1 row/4 columns, next row, 2 columns no colspan, + 1 column colspan="2"

here's existing code:

        echo '<table width="100%" cellpadding="10" cellspacing="5">' . php_eol;          $colspan = 4;         $rows = 0;         for($i = 0; $i < $tmpct; $i++) {             // @ column 0 create new row <tr>             if($i % $colspan == 0) {                 $rows++;                 echo "<tr>\n";             }             // if 1 item in row, need add colspan="4", 2 items colspan="2" 2 <td>'s, 3 items 1 @ colspan="2" + 2 <td>'s             echo '<td width="25%" align="center" valign="middle">' . $tmpret[$i]['sponname'] . '</td>' . php_eol;              // @ column 3 end row </tr>             echo $i % $colspan == 3 ? "</tr>\n" : "";         }         // have 5 columns, need create 3 empty <td> validate table!         for($j = $i; $j < ($colspan * $rows); $j++) {             echo "<td>&nbsp;</td>\n";         }         // add final <tr>         if(($colspan * $rows) > $i) {             echo "</tr>\n";         }           echo '</table>';

well, when arithmetic useful !
need use modulo operation @ each level.

here solution:

$tmpret = array(     array(1),     array(1, 2, 3),     array(1, 2, 3, 4, 5, 6, 7),      array(1, 2, 3, 4, 5),     array(1, 2),     array(1, 2, 3, 4, 5, 6),      array(),     array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16),     array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10) ); $lencol = count($tmpret);  echo '<table border="1" width="800px" cellpadding="10" cellspacing="5">'.php_eol; $colspan = 4;  for($i = 0; $i < $lencol; $i++) {   $bg = 'style="background-color: #'.rand(100, 999).'"';   $row = $tmpret[$i];   $lc = count($row);   $offset = 0;    if ($lc>$colspan) {     $ct = floor($lc/$colspan);     $offset = $ct * $colspan;       $m = 0;     ($k = 0; $k<$ct; $k++) {       echo '<tr '.$bg.' >';       ($l = 0; $l<$colspan; $l++) {         echo '<td>'.$row[$m].'</td>';         $m++;       }       echo '<tr>';     }   }   $mod = $lc % $colspan;   switch ($mod) {     case 1:       echo '<tr '.$bg.' ><td colspan="4">'.$row[$offset].'</td></tr>';     break;     case 2:       echo '<tr '.$bg.' ><td colspan="2">'.$row[$offset].'</td><td colspan="2">'.$row[$offset+1].'</td></tr>';     break;     case 3:       echo '<tr '.$bg.' ><td>'.$row[$offset].'</td><td>'.$row[$offset+1].'</td><td colspan="2">'.$row[$offset+2].'</td></tr>';     break;   } }  echo '</table>';

and looks like:

example

hope helps

edit: works $colspan=4, if need things more dynamic think of replacing switch statement else... maybe nested loops...
