                    'B1:D1',
                    [
                        'borders' => [
                            'outline' => [
                                'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THICK,
                                'color' => ['argb' => 'EB2B02'],
                            ],
                        ]
                    ]
                );
            },
        ];
    }
}

There exist error like this :

Method Maatwebsite\Excel\Sheet::styleCells does not exist.

How can I solve this error?
