在 laravel excel 中的集合末尾放置一列

Question

我有一个 excel 文件，其中包含获取社区的查询以及每个社区的总记录。但是当查询的所有数据都放在 excel 自定义列中时，我怎么能把它放在最后呢？这是我的代码

class NeighborhoodExport implements FromCollection,WithHeadings, ShouldAutoSize, WithEvents,WithTitle
{
    /* *
    * @return \Illuminate\Support\Collection
    */

    protected $start;
    protected $end;
    function __construct($start,$end) {
        $this->start = $start;
        $this->end = $end;
    }
    /**
    * @return \Illuminate\Support\Collection
    */
    public function title(): string
    {
        return 'Neighborhood';
    }
    public function collection()
    {
        return DB::table('users')->select("neighborhood"),DB::raw("COUNT(neighborhoods) as count"))
        ->whereBetween('created_at', [$this->start, $this->end])
        ->groupBy('neighborhood')->get();

    }

    public function headings(): array
    {
        return [
        'Neighborhood',
        'Count',
        ];
    }
    public function registerEvents(): array
    {
        return [
            AfterSheet::class    => function(AfterSheet $event) {
                $cellRange = 'A1:B1'; // All headers
                $styleArray = [
                    'font' => [
                        'name'      =>  'Calibri',
                        'size'      =>  11,
                        'bold'      =>  false,
                        'color' => ['argb' => 'FFFFFF'],
                    ],
                      //Set background style
                      'fill' => [
                        'fillType' => \PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID,
                        'startColor' => [
                            'rgb' => '000000',
                         ]
                    ],
                ];
                $event->sheet->getDelegate()->getStyle($cellRange)->applyFromArray($styleArray);
              },
        ];

    }
}

excel中有一个列总数的例子。就这样

我在文档中找到了函数 registerEvents 上的追加事件。这就是我的代码现在的样子

 public function registerEvents(): array
    {
        return [
            AfterSheet::class    => function(AfterSheet $event) {
                $cellRange = 'A1:B1'; // All headers
                $styleArray = [
                    'font' => [
                        'name'      =>  'Calibri',
                        'size'      =>  11,
                        'bold'      =>  false,
                        'color' => ['argb' => 'FFFFFF'],
                    ],
                      //Set background style
                      'fill' => [
                        'fillType' => \PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID,
                        'startColor' => [
                            'rgb' => '000000',
                         ]
                    ],
                ];
 $total = User::select('neighborhood')->whereBetween('created_at', [$this->start, $this->end])->count();
    $event->sheet->appendRows(array(
                    array('Total', $total),
                    //....
                ), $event);
                $event->sheet->getDelegate()->getStyle($cellRange)->applyFromArray($styleArray);
              },
        ];
