Jak mogę utworzyć macierz wstawki CI, która jest podobna

$data = array(
   array(
      'title' => 'My title' ,
      'name' => 'My Name' ,
      'date' => 'My date'
   ),
   array(
      'title' => 'Another title' ,
      'name' => 'Another Name' ,
      'date' => 'Another date'
   )
);

z mojej normalnej tablicy, która jest

Array
(
    [0] => Array
        (
            [track_id] => 
            [camp_id] => 1
            [field_name] => email_title
            [field_value] => sample
        )

    [1] => Array
        (
            [track_id] => 
            [camp_id] => 1
            [field_name] => email_date
            [field_value] => 2013-07-02
        )

    [2] => Array
        (
            [track_id] => 
            [camp_id] => 1
            [field_name] => email_template
            [field_value] => 2
        )
)
