Laravel excel 将复杂 headers 添加到导出

Question

我需要通过 Laravel Excel 导出带有复杂标题的 sheet。我需要一个主标题和另一个 sub-level 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"  
            ],
        ];
    }
}

但是得到 header 列，例如 [“账户 1 id”、“账户 1 分行”]

有没有办法存档这个任务？

Answer 1

终于，我成功了。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"  
        ];
    }
}

这里我添加了 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。
