 <p>Just modify the '<strong>static function order ( $request, $columns )</strong>' function in '<strong>ssp.class.php</strong>':</p> <pre><code>if ( $column['db'] == 'Nr' ) { // Natural Sort $orderBy[] = 'LENGTH(`' . $column['db'] . '`) ' . $dir . ', ' . '`' . $column['db'] . '` ' . $dir; } else { $orderBy[] = '`' . $column['db'] . '` ' . $dir; } </code></pre> <p>From now on the column with the name '<strong>Nr</strong>' will have natural sort.</p>
