Answer 1

Add ->groupBy('user_id') in your query, this should fix your problem

Answer 2

Try this.
public function TeamTask(Request $request)
{
if ($request->ajax()) {
$data = DB::table('posts')->select('name','user_id')->selectraw('count(user_id) as total')->selectRaw('SUM(status = "Done") as done')->where('div', Auth::user()->div)->groupBy('name')->get();
return Datatables::of($data)
->addColumn('action', function ($row) {
$btn = ' <span class="fas fa-info"></span>';
return $btn;
})
->rawColumns(['action'])
->addIndexColumn()
->make(true);
}
return view('task.teamTask',);
}
