passing parameters to a table

First of all I thought of using $override to pass variables, but I didn't like that, so I ended removing override and passing a $options array with the paramters, the table definition will construct its query depending of the options.
The changes I made to the code are:

* function ajaxtable_render($id,$uid='',$refresh=FALSE,$input_value='',$options=NULL) {
I needed some way of passing the variables to the table; I had to change some other lines of the module so the table definition is called with the $options, and the ajax uses it when request for a refresh.

*Menu system:
<? $items[] = array('path' => 'comptacau/proveidors/despeses',
'title' => t('Page title'),
'callback' => 'ajaxtable_render',
'callback arguments' => array(
"id" => "comptacau_taula_despeses",
"uid" => $user->uid,
"refresh" => false,
"input_value" => '',
"options" => array("supplier_nid" => arg(3)),
),
'access' => true,
'type' => MENU_CALLBACK);
?>
Here it receive a nid and passes it to the table, it will construct the query according to the nid. I didn't change the parameters order so it is full compatible with previous version.
If calling it inside a page it must be called with ajaxtable_render('my_table', $user->uid,FALSE, '', array('assentament_nid'=>$node->nid)

With my code you can list all nodes published by a used; all the nodes from a month, etc...

An example of a table definition is pasted below; I commented some lines of the provided examples, and I use SESSION variables also.

function ajaxtable_table_comptacau_taula_despeses($options=false) {
  $search_inputs = array(
    array(
     ),
  );
  // Get the inputs so they can be added to search
  $inputs = ajaxtable_search_inputs($search_inputs);
  // Alter the theme's search bar template to include the
  // additional search inputs.
  $theme['search'] =  '
     <table class="ajaxtable-default-search-table">'
       .'<tr>'
         .'<td class="ajaxtable-default-search-table-left"></td>'
         .'<td>{search_help}</td><td>'.t('Search for').' {search_input} </td>'
         .'<td>{search_button}</td>'
         .'<td class="ajaxtable-default-search-table-right"></td>'
       .'</tr>'
     .'</table>'
     .'';
    
  // Change the text of the buttons
  $theme['button_text'] =  array(
    'search' => t('Search'),
    'jump' => t('Jump to page'),
    'next' => '>>',
    'prev' => '<<',
  );
  $table = array(

  return $table;

}

I am still working in this table, but it works right now.
