controller

  public function user_management() {
$crud = new grocery_CRUD();
$crud->set_table('user');
$crud->set_subject('User');
$output = $crud->render();
$this->template->set_layout('blog');
$this->template->set('output', (array) $output);
$this->template->title('home', 'Grocery-Crud');
$this->template->build('grocery');
}

in view

<?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; ?>

<div>
    <?php echo $output['output']; ?>
</div>
