Laravel Yajra DataTable:如何阻止索引列(具有行序列号)在其他列被排序时更改

use Yajra\DataTables\DataTables;

public function index()
{
    $dataTable = DataTables::of($data)
        ->addColumn('index', function ($row) {
            return $row->id;
        })
        ->addColumn('name', function ($row) {
            return $row->name;
        })
        ->addColumn('email', function ($row) {
            return $row->email;
        })
        ->rawColumns(['index'])
        ->order([[1, 'asc']]) // 默认按照第一列升序排序
        ->setRowId('id');

    return $dataTable->make(true);
}

$(document).ready(function() {
    $('#dataTable').DataTable({
        processing: true,
        serverSide: true,
        ajax: "{{ route('dataTable.index') }}",
        columns: [
            { data: 'index', name: 'index', orderable: false, searchable: false },
            { data: 'name', name: 'name' },
            { data: 'email', name: 'email' }
        ]
    });
});
