laravel-datatable：我无法浏览集合

Question

我有以下这种格式的收藏

fee

这是我的控制器和数据表的代码

[
{
activitydate: "2019-07-08",
producidos: 1693,
muertos: 0,
propagados: 2,
stock: 1691
},
{
activitydate: "2019-07-05",
producidos: 18,
muertos: 0,
propagados: 0,
stock: 18
},
{
activitydate: "2019-07-04",
producidos: 14,
muertos: 0,
propagados: 0,
stock: 14
}
]

javascript代码

$final_c=collect();
....
.....
...
    $final_c->push([
    "activitydate"=>$key,
    "producidos"=>$producidos,
    "muertos"=>$muertos,
    "propagados"=>$propagados,
    "stock"=>$stock
    ]);
    }

          return $this->ajax($final_c);

          public function ajax($activity)
        {
            return Datatables::of($activity)


                ->addColumn('activitydate',function($activity)
                {
                    return $activity->activitydate;
                })
                ->addColumn('producidos',function($activity)
                {
                    return $activity->producidos;
                })
                ->addColumn('muertos',function($activity)
                {
                    return $activity->muertos;

                })

                ->addColumn('propagados',function($activity)
                {

                    return $activity->propagados;

                })

                ->addColumn('stock',function($activity)
                {
                    return $activity->stock;

                })->rawColumns(['activitydate','producidos','muertos','propagados','stock'])->make(true);
        }

当我尝试通过它时，我会得到

  

异常消息：↵↵试图获取非对象的属性

但是，如果我更改数据表中的值的方式，则会得到以下信息

代码已更改

    function makeColumns()
        {
            return [
                { data: 'activitydate',    className: "text-center" , orderable: false, searchable: false},
                { data: 'producidos',    className: "text-center"      },
                { data: 'muertos',    className: "text-center"        },
                { data: 'propagados',    className: "text-center"       },
                { data: 'stock',    className: "text-center"      },

            ];
        }

$('#up_table').DataTable({
        processing: true,
        serverSide: true,

        },
        columns: makeColumns(),

                {
                    var column = this;
                    //added class "select"
                    var select = $('<select class="select" multiple="multiple" PlaceHolder="SELECCIONAR"><option value=""></option></select>')
                        .appendTo($(column.footer())
                            .empty())
                        .on('change', function()
                        {
                            var vals = $('option:selected', this).map(function(index, element) {
                                return $.fn.dataTable.util.escapeRegex($(element).val());
                            }).toArray().join('|');

                            column  .search(vals.length > 0 ? '' + vals + '' : '', true, false)
                                .draw();
                        });

                    column  .data()
                        .unique()
                        .sort()
                        .each(function(d, j)
                        {
                            select.append('<option value="' + d + '">' + d + '</option>')
                        });
                });
            //select2 init for .select class

        }*/
    });

  

DataTables警告：表id = up_table-请求第0行第0列的未知参数'id'。有关此错误的更多信息，请

在“网络”标签中，我可以看到获得的数据，如下所示：

  public function ajax($activity)
{
    return Datatables::of($activity)


        ->addColumn('activitydate',function($activity)
        {
            return $activity["activitydate"];
        })
        ->addColumn('producidos',function($activity)
        {
            return $activity["producidos"];
        })
        ->addColumn('muertos',function($activity)
        {
            return $activity["muertos"];

        })

        ->addColumn('propagados',function($activity)
        {

            return $activity["propagados"];

        })

        ->addColumn('stock',function($activity)
        {
            return $activity["stock"];

        })->rawColumns(['activitydate','producidos','muertos','propagados','stock'])->make(true);
}

数据表需要什么样的格式？
