How can I display data in two colums?

I need to show some data in two colums, I make a search and find some things and I try. I think that what I do It works but I was rong, works partially.

This is my database

  **Type**
--------
    id_type | type  
------------|------------
     1      |  first Title
     2      |  second Title
     3      |  Third Title

**Content**
---------
id_content | content   | id_type
-----------|-----------|---------
1          | Content1  |   1
2          | Content2  |   2
3          | Content3  |   2
4          | Content4  |   3
5          | Content5  |   3
6          | Content6  |   3

my model

$query1 = "select * from type";
$query2 = "select * from content where id_type = $id_type";

Note: this query goes in ther respective function

my controller

$list_content = array(array());
$contador = 0;
$list_type = array(array());
$cont_type = 0;
            $query1 = $obj->Search_Type();
  for ($j = 0; $j < $query1->num_rows; $j++) {

    $id_type = $list_type[$cont_type]['id_type'] = $query1->row($j)->id_type;

    $query2 = $obj->Search_Content($id_type);

      for ($i = 0; $i < $query2->num_rows; $i++) {

       id_content = $list_content[$contador]['id_content'] = $query2->row($i)->id_content;
         $list_content[$contador]['id_type'] = $query2->row($i)->id_type;
         $contador++;
         } //end for i

      $list_type[$cont_type]['id_receptor'] = $id_content; 
      $cont_type++;

            }//del for j

in my view

<table border='1'>
<?php $columna = 1;
 for ($j = 0; $j < $cont_type; $j++) {
    if ($list_type[$j]['id_type'] != '') {
 ?>
<tr>
    <td colspan = '2'> 
    <?php echo $list_tipo_receptor[$j]['tipo_receptor_TVD']; ?>
    </td>
</tr>
<?php
    }// if type no empty
    for ($i = 0; $i < $contador; $i++) {
       if ($list_type[$j]['id_type'] == $list_content[$i]['id_type']) {
          if ($columna == 1) {
          ?>
          <tr>
            <?php } ?>
             td> <?php echo $list_content[$i]['id_content']; ?></td>
              <?php if ($columna != 1) { ?>
          </tr>
             <?php
             $columna = 1;
              }// if columna != 1
              else {
                    $columna++;
                   }// else
                  }//if
             } //for i
