The following:

        $columns = array();
        foreach($form as $f)
        {
            $columns += array($f['form_field_id'] => $f['label']);
        }

Will create.
Array
(
    [] => 
    [J] => J
    [1] => Title
    [3] => Recruiter
    [2] => Description
    [4] => Job_Type
    [5] => Segment
    [6] => Owner
)

And this will create:

        $columns = array();
        foreach($form as $f)
        {
            $columns[] = array($f['form_field_id'] => $f['label']);
        }
