I got it to work with static html data as shown in this jsfiddle:
http://jsfiddle.net/L7PNV/
by specifying
aoColumns: {\"sType\": \"natural\"}
<
Just modify the 'static function order ( $request, $columns )' function in 'ssp.class.php':
if ( $column['db'] == 'Nr' ) {
// Natural Sort
$orderBy[] = 'LENGTH(`' . $column['db'] . '`) ' . $dir . ', ' . '`' . $column['db'] . '` ' . $dir;
} else {
$orderBy[] = '`' . $column['db'] . '` ' . $dir;
}
From now on the column with the name 'Nr' will have natural sort.
