jquery datatable server side multi column filter

nanogr000

I am using jquery datatables to load data server side into my table:
https://datatables.net/examples/data_sources/server_side

I have set a class whitch return me the formatted json string:

$columns = array(
array( 'db' => 'first_name', 'dt' => 0 ),
array( 'db' => 'last_name',  'dt' => 1 ),
array( 'db' => 'position',   'dt' => 2 ),
array( 'db' => 'office',     'dt' => 3 ),
array(
    'db'        => 'start_date',
    'dt'        => 4,
    'formatter' => function( $d, $row ) {
        return date( 'jS M y', strtotime($d));
    }
),
array(
    'db'        => 'salary',
    'dt'        => 5,
    'formatter' => function( $d, $row ) {
        return '$'.number_format($d);
    }
)

How is it possbile to get multiple db inside an array? For example I would like to combine first_name and last_name inside a column

It might be easier to do it on the client-side, see example here - it's putting the age column into the first name, similar to what you would do with the two names,
