CodeIgniter's HTML Table Class with Form Helper

Is it possible to use Form Helper "inside" HTML Table Class in CodeIgniter?

This is what I mean:

$this->load->library('table');
$this->load->helper('form');
form_open('example/function')

$data = array(
             array(form_checkbox('newsletter', 'accept', TRUE), form_checkbox('newsletter', 'accept', TRUE),),
             );

echo $this->table->generate($data);

Of course this is possible, the form helper return only string so you can do something like that :

<?php

class Welcome extends CI_Controller {
    public function index()
    {
        $this->load->library('table');
        $this->load->helper('form');

        $data = array(
            array('Label', 'Input'),
            array('Name', form_input('name')),
            array('Firstname', form_input('firstname'))
        );

        echo $this->table->generate($data);
    }
}
