Laravel Excel，从模型导出，样式问题

使用Laravel Excel库可以轻松地从模型中导出数据，并且还可以应用自定义的样式。这使得数据导出变得非常方便，无论是将数据用于报表生成还是导入到其他应用程序中。

php
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\WithStyles;
use PhpOffice\PhpSpreadsheet\Worksheet\Worksheet;
class UsersExport implements FromCollection, WithHeadings, ShouldAutoSize, WithStyles
{
    public function collection()
    {
        return User::all();
    }
    public function headings(): array
    {
        return [
            'ID',
            'Name',
            'Email',
        ];
    }
    public function styles(Worksheet $sheet)
    {
        return [
            1 => ['font' => ['bold' => true]],
        ];
    }
}

php
public function styles(Worksheet $sheet)
{
    return [
        1 => [
            'font' => ['bold' => true],
            'fill' => [
                'fillType' => \PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID,
                'startColor' => ['rgb' => 'FF0000'],
            ],
            'borders' => [
                'allBorders' => [
                    'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN,
                    'color' => ['rgb' => '000000'],
                ],
            ],
        ],
    ];
}
