Laravel Excel Export - From View not working

I tried to implement exporting to excel file From View approach using the Laravel Excel. Here is the link of the documentation https://laravel-excel.maatwebsite.nl/3.1/exports/from-view.html. But I can't figure it out yet referencing the example shown in the website. It returns an error saying PhpOffice \ PhpSpreadsheet \ Writer \ Exception Invalid parameters passed. . I've been changing my codes trying to solve this but no luck at all. Please help me figure this out. Below are my codes. Thank you.

LoansExport.php

<?php

namespace App\Exports;

use App\Loan;

use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;

class LoansExport implements FromView
{
public function view(): View
{
    return view('partials.view_loan_export', [
        'loans' => Loan::all()
    ]);
 }
}

view_loan_export.blade.php

<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<table>
    <thead>
    <tr>
        <th>First Name</th>
        <th>Last Name</th>
    </tr>
    </thead>
    <tbody>
   @foreach ($loans as $loan)
        <tr>
           <td >{{ $loan->member->fname }}</td>
           <td >{{ $loan->member->lname }}</td>
        </tr>
    @endforeach
    </tbody>
   </table>
 </body>

LoansController.php

<?php

namespace App\Http\Controllers;
use App\Loan as Loan;
use App\Member as Member;

use Illuminate\Http\Request;
use App\Exports\LoansExport;
use Maatwebsite\Excel\Facades\Excel;

class LoansController extends Controller
{

public function loanexport() 
{
    return Excel::download(new LoansExport, 'loans.xlsx');
}

}

web.php

Route::get('/loanexport', 'LoansController@loanexport');

Solution

  • just put the table tag and the tag within it in your view

    <table>
    <thead>
    <tr>
        <th>First Name</th>
        <th>Last Name</th>
    </tr>
    </thead>
    <tbody>
   @foreach ($loans as $loan)
        <tr>
           <td >{{ $loan->member->fname }}</td>
           <td >{{ $loan->member->lname }}</td>
        </tr>
    @endforeach
    </tbody>
   </table>
