I was trying to pass some extra values of data on grocery crud view when I came up with the following solution.
This is my controller :
$crud = new grocery_CRUD();
$crud->set_table('tickets');
$crud->set_subject('Order'); 
$output = $crud->render();
       $data = array(
    'title' => "Unsolved Tickets ! ",                       
       'page_heading' => "Unsolved tickets ! ",                       
       'output'      =>  $output,
       );      
$this->load->view('example',$data);  
and this is my view file :  
<?php  
foreach($output->css_files as $file): ?>
<link type="text/css" rel="stylesheet" href="<?php echo $file; ?>" />
<?php endforeach; ?>
<?php foreach($output->js_files as $file):  ?>
<script src="<?php echo $file; ?>"></script>
<?php endforeach; ?>
                        <?php echo $output->output;   ?>
