Laravel :Try Download Excel : Class 'XMLWriter' not found - excel

Question

I am trying download html table as excel file, first in blade template I did this :
<form method="POST" action="{{url('/download')}}" id="download_form">
{{ csrf_field() }}
<table class="table font-weight-bold w-100" id="excel_table">
...........
<button type="submit" id="download" class="btn btn-success">Download to excel</button>
</div>
</form>
<script>
$(document).ready(function(){
$('#download').click(function(){
var table_content = '<table>';
table_content += $('#excel_table').html();
table_content+= '</table>';
$('#file_contente').val(table_content);
$('#download_form').html();
})
})
</script>
the in controller I tried this :
namespace App\Http\Controllers;
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Shared\XMLWriter;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
public function download(Request $req)
{
$filename = $req->stage." ".$req->group . '.xlsx';
$temporary_html_file = './tmp_html/' .time() . '.html';
file_put_contents($temporary_html_file, $req->file_contente);
$reader = IOFactory::createReader('Html');
$spreadsheet = $reader->load($temporary_html_file);
$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save($filename);
header('Content-Type: application/x-www-form-urlencoded');
header('Content-Transfer-Encoding: Binary');
header("Content-disposition: attachment; filename=\"".$filename."\"");
readfile($filename);
unlink($temporary_html_file);
unlink($filename);
}
I get this error :
Class 'XMLWriter' not found A class import is missing You have a
missing class import. Try importing this class:
PhpOffice\PhpSpreadsheet\Shared\XMLWriter.
Note the download is works correctly in locahost server
