Add export PDF with post as a method.

[jiwom]

Use exportPostPdf as button. This button is recommended for IE browsers since IE has URL length limit.

[jiwom]

change exportPostPdf to postPdf

sample code would be

public function html()
{
    return $this->builder()
        ->columns($this->getColumns())
        ->parameters([
            'buttons' => ['postPdf'],
        ]);
}

Take note of adding CSRF token

<meta name="csrf-token" content="{{ csrf_token() }}" />
<script type="text/javascript">
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
</script>

Take note of your Routing

$router->post('sample/export', SampleController::class . '@index');
