[Help] Problem with a query

[eluser]antoniog[/eluser]
Hi all,
I set the model, which reproduce the code to follow, on the page to print the data extracted from the database table that is referenced by the query.
The query works well as an example in the User Guide but I'd need to print the values ​​obtained in the exact spots on the page and not as high as in the example.
What changes should I make?
I tried other queries but this is what works best.

Model code:

Code:

<?php
class MListe extends CI_Model {

    function __construct()
    {
      $this->load->database();
    }

    public function getDettagli()
    {
      $dettagli = $this->db->query("SELECT numero_link, raggio_pr, prezzo FROM spp_liste");

      if ($dettagli->num_rows() > 0)
      {
        $row = $dettagli->row_array(1);

        echo $row['numero_link'];
        echo $row['raggio_pr'];
        echo $row['prezzo'];
      }
    $dettagli->free_result();
    }

}

Page code:

Code:
