How to loop array of array in in laravel and display all data base in its date created in blade

Good day, I want to loop the array inside of array, I already group all the data, base in its date created, now I want to display all data base on its date created to blade. I want to get all data and place in its date if there are multiple data in its date. I hope you get my point ,please help I'm just new here thank you.

this is my controller ,,

      $job_order = JobOrder::whereNotNull(['er_total','mf_total','calib_total','overall_total','created_at'])
               ->when($this->start_date && $this->end_date, function ($query) {
                  $query->where('created_at', '>=', $this->start_date);
                  $query->where('created_at','<=', Carbon::parse($this->end_date)->addHour(23)- 
              >addMinute(59)->addSecond(59));
            })->get()->groupBy(function($item) {
                return $item->created_at->format('Y-m-d');
               });

and this is my blade ,,

      @foreach($job_order as $key => $data)   
                         
                              {{-- @dd($data[0]['er_total']) --}}
                                <tr>
                                    <td style="border: 1px solid black; font-weight: bold" colspan="3">{{ $data->created_at->format('Y-m-d') ?? ''}}</td>
                                </tr>
                              
                                <tr> 
                                    <td style="text-align: right; border: 1px solid black ">Engine Recon</td>
                                    <td style="text-align: right; border: 1px solid black ">{{ $data->csa == 1 && $data->er_total != 0.00 ? number_format($data->er_total, 2) : 0 }}</td>
                                    <td style="text-align: right; border: 1px solid black ">{{ $data->csa == 2 && $data->er_total != 0.00 ? number_format($data->er_total, 2) : 0 }}</td>
                                </tr>
                                <tr>
                                    <td style="text-align: right; border: 1px solid black ">Machining & Fabr.</td>
                                    <td style="text-align: right; border: 1px solid black ">{{ $data->csa == 1 && $data->mf_total != 0.00 ? number_format($data->mf_total, 2): 0 }}</td>
                                    <td style="text-align: right; border: 1px solid black ">{{ $data->csa == 2 && $data->mf_total != 0.00 ? number_format($data->mf_total, 2) : 0 }}</td>
                                </tr>
