Is this the correct way to add custom data in specific column?

[cooperinho]

I want to combine 2 database columns to one Yajra column.
this is how I do it:

First, I set the columns in getColumn():

    protected function getColumns()
    {
        return [
            ['title' => 'Id', 'data' => 'id'],           
            ['title' => 'Item Information', 'data' => 'item_information'],

Then I add column in dataTable() with empty content:

    public function dataTable($query)
    {
        return datatables()
            ->eloquent($query)
            ->addColumn('item_information', '') // empty content

Then I render it using columnDefs:

    public function html()
    {
        return $this->builder()
         ->parameters([
                'columnDefs' => [
                    [
                        'targets' => [1],
                        'render' => 'function (data, type, row) {
                            return "row.id + " - " + row.name;
                        }'

Or there is a better way to do it?
