如何在laravel excel版本3中添加列的标题和总和值?

问题描述 投票:0回答:1

我从这里得到了参考:https://laravel-excel.maatwebsite.nl/docs/3.0/getting-started/basics

所以我使用版本3

我的控制器是这样的:

public function exportToExcel(Request $request)
{
    $data = $request->all();
    $exporter = app()->makeWith(SummaryExport::class, compact('data'));   
    return $exporter->download('Summary.xlsx');
}

我的脚本导出为ex​​cel,如下所示:

namespace App\Exports;
use App\Repositories\ItemRepository;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithHeadings;
class SummaryExport implements FromCollection, WithHeadings {
    use Exportable;
    protected $itemRepository;
    protected $data;
    public function __construct(ItemRepository $itemRepository, $data) {
        $this->itemRepository = $itemRepository;
        $this->data = $data;
    }
    public function collection()
    {
        $items = $this->itemRepository->getSummary($this->data);
        return $items;
    }
    public function headings(): array
    {
        return [
            'No',
            'Item Number',
            'Sold Quantity',
            'Profit'
        ];
    }
}

如果脚本执行,结果如下:

我想在表格上方添加一些描述或标题,我想将销售数量列和利润列相加

所以我想要这样的结果:

我已阅读文档并在谷歌搜索,但我找不到解决方案

有人可以提供帮助吗?

更新

从这个参考:https://laravel-excel.maatwebsite.nl/docs/3.0/export/extending

我尝试添加:

....
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\BeforeExport;
use Maatwebsite\Excel\Events\BeforeWriting;
use Maatwebsite\Excel\Events\BeforeSheet;
use Maatwebsite\Excel\Events\AfterSheet;
class SummaryExport implements FromCollection, WithHeadings, WithColumnFormatting, ShouldAutoSize, WithEvents
{
    ...
    public function registerEvents(): array
    {
        return [
            BeforeExport::class  => function(BeforeExport $event) {
                $event->writer->setCreator('Patrick');
            },
            AfterSheet::class    => function(AfterSheet $event) {
                $event->sheet->setOrientation(\PhpOffice\PhpSpreadsheet\Worksheet\PageSetup::ORIENTATION_LANDSCAPE);

                $event->sheet->styleCells(
                    'B2:G8',
                    [
                        'borders' => [
                            'outline' => [
                                'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THICK,
                                'color' => ['argb' => 'FFFF0000'],
                            ],
                        ]
                    ]
                );
            },
        ];
    }
}

在我上面的脚本中

但是存在这样的错误:

Method Maatwebsite\Excel\Sheet::styleCells does not exist
Method Maatwebsite\Excel\Sheet::setOrientation does not exist.
Method Maatwebsite\Excel\Writer::setCreator does not exist.

我该如何解决错误?

你必须像这样实例化一个数组: -

$export = [];

然后你必须使用array_push将数据推入其中: -

array_push($export, [
                    'No' => '',
                    'item'=>'',
                    'sold' =>'',
                    'profit' => ''
                ]);

然后你可以像这样附加你的计算: -

array_push($export,[' ','Items Count:', '=COUNTA(C2:C'.$Count.')' ,' ','Profit Sum:', '=SUM(D2:D'.$Count.')']);

如果你添加任何标题,$ count = count($ array + 1)。

并且您可以使用正常的细胞功能。
