Update checkbox status from server side

[WillYouth]

Let me explain the use case first:
I want to be able to edit a form with a table with rows of checkboxes. How can I checked the selected items based on what is stored in my database?
Here are my controller:

// called from Datatables AJAX
public function getEditServiceItemList(Request $request, $id)
  {
      if ($request->ajax()) {
          $items = Item::latest()->get();
          $service = Service::find($id);
          // foreach($service->serviceItems as $serviceItem)

          return Datatables::of($items)
              ->addIndexColumn()
              ->addColumn('checkbox', function ($row) {
                  $checkbox = "<input type='checkbox' name='items[]' value='$row->id'>";
                  return $checkbox;
              })
              ->rawColumns(['checkbox'])
              ->make(true);
      }
  }

// call from browser GET
public function edit($id)
  {
      $service = Service::find($id);
      $sites = Site::get(["name", "id", 'zone']);
      $engineers = User::whereHas(
          'roles',
          function ($q) {
              $q->where('name', 'Engineer');
          }
      )->get();
      return view('services.edit', compact('sites', 'engineers', 'service'));
  }

Here's my Datatables AJAX:

table = $('#serviceItemList').DataTable({
      processing: true,
      serverSide: true,
      scrollResize: false,
      scrollY: 300,
      scrollCollapse: true,
      paging: false,
      info: false,
      createdRow: function (row, data, dataIndex) {
          $(row).attr('data-id', data.id);
      },
      dom: 'Bfrtip',
      ajax: {
          'url': "/service/showAddedItem/"+$('#editServiceForm').attr('action').split('/').pop(),
          'type': "POST",
      },
      columns: [
          { data: 'checkbox', name: 'items[]' },
          { data: 'DT_RowIndex', name: 'DT_RowIndex' },
          { data: 'code', name: 'code', orderable: true, },
          { data: 'description', name: 'description', searchable: true },
      ],
      select: {
          style: 'multi',
          selector: 'td:first-child'
      },
  });

HTML table:

<table class="table table-bordered" id="serviceItemList">
    <thead>
        <tr>
            <th></th>
            <th>No</th>
            <th>Code</th>
            <th>Description</th>
        </tr>
    </thead>
    <tbody>
    </tbody>
</table>
