如何更改csv导出的列的格式-Laravel Excel

Question

我用laravel-excel 3.1导出了一个csv文件，并且在检查值时将其括在引号中，因此它们以字符串形式导出，但我需要将其键入数字类型中]]

导出的csv文件：

"ano_plantacion","zona","sitio","manejo","sup_ha","codigo","rpend" "2018","87","3","10","30.69","2042201801","" "2017","87","3","10","14.86","2042201701",""

我想要或应该是：

ano_plantacion,zona,sitio,manejo,sup_ha,codigo,rpend 2018,87,3,10,30.69,2042201801, 2017,87,3,10,14.86,2042201701,

Class SuperImport：

<?php

namespace App\Exports;

use App\Super;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;
use PhpOffice\PhpSpreadsheet\Style\NumberFormat;
use Maatwebsite\Excel\Concerns\WithColumnFormatting;


class SuperExport implements FromCollection,WithHeadings, WithColumnFormatting

    use Exportable;

    protected $superficie;

    public function __construct($superficie = null)
    
        $this->superficie = $superficie;
    
    public function headings(): array
    
        return [
            'ano_plantacion',
            'zona',
            'sitio',
            'manejo',
            'sup_ha',
            'codigo',
            'rpend',

        ];
    

    public function columnFormats(): array
    
        return [
            'A' => NumberFormat::FORMAT_GENERAL,
            'B' => NumberFormat::FORMAT_GENERAL,
            'C' => NumberFormat::FORMAT_GENERAL,
            'D' => NumberFormat::FORMAT_GENERAL,
            'E' => NumberFormat::FORMAT_GENERAL,
            'F' => NumberFormat::FORMAT_GENERAL,
            'G' => NumberFormat::FORMAT_GENERAL,
        ];
    

    /**
    * @return \Illuminate\Support\Collection
    */
    public function collection()
    
        return $this->superficie ?: Super::all();
    

控制器：

$super = Super::select('ano_plantacion','zona','sitio', 'manejo','sup_ha','codigo','rpend')->get();
Excel::store( new SuperExport($super), 'export/Super.csv' );
假设使用columnFormats()方法可以更改格式，但是我在文档中看不到可用的格式，并且在执行代码时问题仍然存在。
