Datatables and ORM Model

Hi
I'm building a new ORM Model, which uses sqlsrv driver and works

PHP Code:

<?php
namespace App\Models;
use CodeIgniter\Model;
class MyModel extends Model
{
    protected $DBGroup = 'sqlserver';
    protected $table = 'project';
    protected $primaryKey = 'idproject';
    protected $useAutoIncrement = true;
    protected $returnType     = 'array';
    protected $useSoftDeletes = true;
    protected $allowedFields = ['name', 'logo'];
    protected $useTimestamps = false;
} 


I load that model from a Library and return data to Controller

Code:

$data = json_encode($this->mymodel->findAll());

Now, I must use Datatables in the view, with serverSide=true and Ajax property pointing to Controller's url

The json format for Datatables is custom and must have additional fields (draw, recordsTotal, data, etc.)
https://datatables.net/manual/server-side

Code:

{
    "draw": 1,
    "recordsTotal": 57,
    "recordsFiltered": 57,
    "data": [
        [
            "Test1",
            "bla",
        ],
        [
            "Test2",
            "bla bla",
        ],
        ...
    ]
}

PS: I've already seen https://github.com/hermawanramadhan/Code...DataTables but it won't fit my needs in future

Does anyone have an example about how to build that custom json using the methods from ORM ?

Thanks a lot for any tip you can give me
