I'm setting up a datatable for users and there privileges from a pivot but im getting a blank screen after following up the documentation these are the files/methodes i used

datatable.js

$(document).ready(function () {
$('#user_table').DataTable({
    processing:true,
    serverSide:true,
    ajax:{
        url: "{{route('utilisateurs')}}",
    },
    columns:[
        {data: 'name',name: 'name'},

        return view('pages.utilisateurs')->with('privileges',$privilege);}

    if ($request->ajax()) {
        $users = User::all();
        return Datatables::of($users)
            ->addColumn('libelle_privilege',function(User $user){
                return $user->privileges()->latest()->first()->libelle_privilege;
            })
            ->make(true);
    }
}

<table class="table table-striped table-bordered bootstrap-3 dataTable 
    server-side" id="user_table" role="grid" aria- 
    describedby="user_table_info">
    <thead>
    <tr role="row">
        <th class="sorting_asc" rowspan="1" colspan="1" aria- 
        sort="ascending">Nom</th>
        <th class="sorting" rowspan="1" colspan="1">CIN</th>

In jS

 var url = "{{ url('/utilisateurs/getData') }}";
    $(document).ready(function () {
$('#user_table').DataTable({
    processing:true,
    serverSide:true,
    ajax:{
        url: url,
    },
    columns:[
        {data: 'name',name: 'name'},
        {data: 'cin',name: 'cin'},
        {data: 'tel',name: 'tel'},
        {data: 'adresse',name: 'adresse'},
        {data: 'email',name: 'email'},
        {data: 'nom_utilisateur',name: 'nom_utilisateur'},
        {data: 'libelle_privilege',name: 'libelle_privilege'},
    ]
});

});

and in controller as you are adding new column

 public function getData(Request $request)
{
    if ($request->ajax()) {
    $users = User::all();
    return Datatables::of($users)
        ->addColumn('libelle_privilege',function(User $user){
            if ($user->privileges()->exists()) {
                $privileges = $user->privileges()->pluck('libelle_privilege')->toArray();
                return implode(" ",$privileges);
            }
            return 'non';
        })
        ->make(true);
}
}

In your view

<table class="table table-striped" id="user_table">
    <thead>
    <tr role="row">
        <th>Name</th>
        <th class="sorting" rowspan="1" colspan="1">CIN</th>
        <th class="sorting" rowspan="1" colspan="1">Téléphone</th>
        <th class="sorting" rowspan="1" colspan="1">Adresse</th>
        <th class="sorting" rowspan="1" colspan="1">Email</th>
        <th class="sorting" rowspan="1" colspan="1">Nom d'utilisateur</th>
        <th class="sorting" rowspan="1" colspan="1">Privilèges</th>
    </tr>
    </thead>
    </table>

make this changes and let me know the status.
