excel - 如何更改 Laravel Excel Maat 网站角色的颜色？

Question

我从这里获取教程:https://laravel-excel.maatwebsite.nl/3.0/exports/extending.html

所以我使用版本3

我的Excel是这样的:

我想把它改成这样:

所以我希望字符England更改为红色和粗体

我尝试这样:

namespace App\Exports;
...
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\BeforeExport;
use Maatwebsite\Excel\Events\AfterSheet;

class SummaryExport implements FromView, WithEvents
{
    ...
    public function registerEvents(): array
    {
        return [
            AfterSheet::class    => function(AfterSheet $event) {
                $event->sheet->styleCells(
                    'B1:D1',
                    [
                        'borders' => [
                            'outline' => [
                                'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THICK,
                                'color' => ['argb' => 'EB2B02'],
                            ],
                        ]
                    ]
                );
            },
        ];
    }
}

存在这样的错误:

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

如何解决这个错误？

Answer 1

您可以在服务提供商的 boot 方法中注册宏。例如 App\Providers\AppServiceProvider 提供程序将如下所示:

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use \Maatwebsite\Excel\Sheet;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //
        Sheet::macro('styleCells', function (Sheet $sheet, string $cellRange, array $style) {
            $sheet->getDelegate()->getStyle($cellRange)->applyFromArray($style);
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

You should create different service provider to resister this kind of macro for isolating third party's concern.

对于字体颜色设置字体样式:

namespace App\Exports;
...
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\BeforeExport;
use Maatwebsite\Excel\Events\AfterSheet;

class SummaryExport implements FromView, WithEvents
{
    ...
    public function registerEvents(): array
    {
        return [
            AfterSheet::class    => function(AfterSheet $event) {
                $event->sheet->styleCells(
                    'B1:D1',
                    [
                        //Set border Style
                        'borders' => [ 
                            'outline' => [
                                'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THICK,
                                'color' => ['argb' => 'EB2B02'],
                            ],
                           
                        ],

                        //Set font style
                        'font' => [
                            'name'      =>  'Calibri',
                            'size'      =>  15,
                            'bold'      =>  true,
                            'color' => ['argb' => 'EB2B02'],
                        ],

                        //Set background style
                        'fill' => [
                            'fillType' => \PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID,
                            'startColor' => [
                                'rgb' => 'dff0d8',
                             ]           
                        ],

                    ]
                );
            },
        ];
    }
}
