problem count rows on table in pagination?

[eluser]SaSa[/eluser]
I have an problem with rownum in following code. it is this that, in each page of pagination rows in table be counted from the beginning. For example, the clear:

P1: If we're on the first page of pagination, rows are the counts:

Code:

1 Columns1
2 Columns2
3 Columns3
4 Columns4

P2: If we're on the second page of pagination, rows are the counts:

Code:

1 Columns5
2 Columns6
3 Columns7
4 Columns8

<br>

P2: The I want to be counted row in table,(on the second page of pagination and ...):

Code:

5 Columns5
6 Columns6
7 Columns7
8 Columns8

P3: ... and more

This code:

Code:

$data['results'] = $this->db->query("SELECT @rownum:=@rownum+1 rownum, t.* ".
            "FROM (SELECT @rownum:=0) r, hotel_submits t ".
            "ORDER BY id desc LIMIT $offset, 4");

Full code:

Code:

function show($offset = 0)
        {
        $this->load->library('pagination');
            $config['base_url'] = base_url().'admin/accommodation/show';
            $config['uri_segment'] = 4;
            $config['total_rows'] = $this->db->count_all('hotel_submits');
            $config['per_page'] = '4';            
            
            $this->pagination->initialize($config);    
                $data['pagination'] = $this->pagination->create_links();                                        

            $offset = (int) $offset; // just to make sure nothing funky gets in here
            $data['results'] = $this->db->query("SELECT @rownum:=@rownum+1 rownum, t.* ".
                "FROM (SELECT @rownum:=0) r, hotel_submits t ".
                "ORDER BY id desc LIMIT $offset, 4");
          
                ////////////////////////                                
                
                $this->load->view('admin/accommodation_submit_show', $data);
    }

How is it?
With respect
