mau tanya tentang pagination di CI

class Buku_model extends Model {
 
	function __construct(){
		parent::Model();
 
	}
 
	function get_buku()
	{
		$query=$this->db->query('select * from buku ORDER BY id_buku');
		return $query->result();
	}
}

class Buku extends Controller {
 
	function Buku()
	{
		parent::Controller();	
		$this->load->database();
		$this->load->helper('url');
	}
 
	function index()
	{
		$this->load->model('rak_model');
		$this->load->model('kategori_model');
		$this->load->model('pengarang_model');
		$this->load->model('penerbit_model');
		$this->load->model('pencetak_model');
		$this->load->library("pagination");   
		$this->load->view('buku');
 
		$config['base_url'] = base_url().'index.php/buku/index/';
		$config['total_rows'] = $this->db->count_all('tabel data');
		$config['per_page'] = '10';
		$this->pagination->initialize($config);
 
		$this->load->model('buku_model');
		$data['results'] = $this->buku_model->get_buku($config['per_page'],$this->uri->segment(3));
 
		// load the HTML Table standart CI
		$this->load->library('table');
		$this->table->set_heading('id_buku', 'jdl_buku', 'isbn', 'thn_terbit');
 
		// load the view menggunakan template
		//$this->init_model->displayTemplate('front/buku', $data);
	}
}
 
code viewnya :
<?php echo $this->table->generate($results);
