Laravel excel 将复杂的标题添加到导出

如何解决Laravel excel 将复杂的标题添加到导出

我需要通过 Laravel Excel 导出带有复杂标题的工作表。我需要一个主标题和另一个子级标题。

我正在尝试这样，

use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\WithHeadings;

class InvoicesExport implements FromQuery,WithHeadings
{   
    public function headings(): array
    {
        return [
            'Account 1' =>[
                "Account 1 id","Account 1 branch"  
            ],'Account 2' =>[
                "Account 2 id","Account 2 branch"  
            ],];
    }
}

但是获取标题列，例如 [ "Account 1 id","Account 1 branch" ]

有没有办法存档这个任务？

解决方法

最后，我设法做到了。添加它，因为它对其他人有用。

use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\WithCustomStartCell;
use Maatwebsite\Excel\Events\AfterSheet;
use Maatwebsite\Excel\Concerns\WithEvents;
use \Maatwebsite\Excel\Sheet;

class InvoicesExport implements FromCollection,WithHeadings,WithCustomStartCell,WithEvents{ 

    public function startCell(): string
    {
        return 'A2';
    }

    public function registerEvents(): array {
        
        return [
            AfterSheet::class => function(AfterSheet $event) {
                /** @var Sheet $sheet */
                $sheet = $event->sheet;

                $sheet->mergeCells('A1:B1');
                $sheet->setCellValue('A1',"Account 1");

                $sheet->mergeCells('C1:D1');
                $sheet->setCellValue('C1',"Account 2");
                
                $styleArray = [
                    'alignment' => [
                        'horizontal' => \PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER,],];
                
                $cellRange = 'A1:D1'; // All headers
                $event->sheet->getDelegate()->getStyle($cellRange)->applyFromArray($styleArray);
            },];
    }
      
    public function headings(): array
    {
        return [
                "Account 1 id","Account 1 branch"  
                "Account 2 id","Account 2 branch"  
        ];
    }
}

嘿嘿，我添加了 startCell() 从第二行开始。 registerEvents() 将第一行单元格与内容合并并居中对齐。
