如何在Laravel中使用Maatwebsite从数据库动态导出header数据到excel

Question

In my case, i have problem like this

Sample table and data:

// Table Account
Id  |  Name  |
 1  |  Kiara |
 2  |  Steve |

My currently code is:

<?php

namespace App\Exports;

use Maatwebsite\Excel\Concerns\FromCollection;
use App\Models\Account;

class ExportTable implements FromCollection
{
    public function collection()
    {
        return Account::all();
    }
}

What i had now in excel:

 1  |  Kiara |
 2  |  Steve |

I want show the headers value as dynamic as table, without more effort like this

    public function headings(): array
    {
        return [
                "Id",
                "Name"  
        ];
    }

Is it posible?

Answer 1

 public function headings(): array
{
    return Illuminate\Support\Facades\Schema::getColumnListing('tableName');

}

Try this

Answer 2

add your model,

public function getTableColumns() 
{
    return $this->getConnection()->getSchemaBuilder()->getColumnListing($this->getTable());
}

and...

public function headings(): array
{
   $model = new Model();

   $columns = $model->getTableColumns();
   return $columns;
}

try this cok.
