my code for register_post_type is –

  1. Assuming the value of the meta box is stored as post meta, you should (a) register a custom column using the dynamic manage_{$post_type}_posts_columns filter hook:

    add_filter( 'manage_brand_posts_columns', 'so20352744_manage_brand_posts_columns', 25, 1 );
function so20352744_manage_brand_posts_columns( $cols )
{
    $cols['brand'] = __( 'Brand', 'txt_domain' );

    return $cols;
}

    and (b) add content to the column using the manage_posts_custom_column action hook:

    add_action( 'manage_posts_custom_column', 'so20352744_manage_posts_custom_column', 2, 1 );
function so20352744_manage_posts_custom_column( $col )
{
    global $post;

    switch ( $col )
    {
        case "brand" :

            if( '' != get_post_meta( $post->ID, 'brand_code', true ) )
                echo get_post_meta( $post->ID, 'brand_code', true );
            else
                echo __( 'N/A', 'txt_domain' );

            break;

        default :
            break;
    }
}

    Both functions go in functions.php. More info: http://codex.wordpress.org/Plugin_API/Action_Reference/manage_posts_custom_column
