Help using jQuery UI Module -> Sortable elements

Hi all !
First of all, my english level is bad, i'm spanish.

The trouble is that, i want to use the jQuery UI Module to sort a list of elements that layout with my theme function. I don't know what drupal function does internally.

Here the code i use to layout the database items :

function metalinks_list() {
	global $user;
	//drupal_set_title(t('Links associats a: @name', array('@name' => $account->name)));
	$max = 20;
	$sql = 'SELECT lid,name,link FROM {metalinks} WHERE uid = %d';
	$header = array(
    array('data' => t('Title'), 'field' => 'name'),
    array('data' => t('Operations'), 'colspan' => 2)
  	); 
  	$result = pager_query(db_rewrite_sql($sql . tablesort_sql($header)), $max, 0, $count_query = NULL, $user->uid);
	$rows = metalinks_build_rows($result);

	$output = '';
  	$output .= theme_metalinks_list($header, $rows, $max);
  	return $output;
 }
  
function metalinks_build_rows($result) {
  global $user;
  $rows = array();
  while ($row = db_fetch_object($result)) {
		$may_edit = TRUE;
		$may_delete = TRUE;
		$rows[] = array(
        	l($row->name,$row->link),
			$may_edit ? l(t('edit'), "metalinks/edit/$row->lid") : '',
			$may_delete ? l(t('delete'), "metalinks/delete/$row->lid") : ''
      );
  }
  return $rows;
}  
  
function metalinks_theme() {
  return array(
    'metalinks_list' => array(
      'arguments' => array('header' => array(), 'rows' => array(), $max = 50),
    ),
  );  
}  
  
function theme_metalinks_list($header, $rows, $max) {
  if ($rows) {
    $pager = theme('pager', NULL, $max, 2);
    if (!empty($pager)) {
      $rows[] = array(array('data' => $pager, 'colspan' => 3));
		jquery_ui_add('ui.sortable');
    }
    $output .= theme('table', $header, $rows);
  }
  else {
    $output = t('Tu espacio está vacío.');
  }
  return $output;
}
