Bootstrap 4：可滚动行，填充剩余高度

PhpSpreadsheet：权限| ZipArchive :: close（）：无法创建临时文件

我想提供一个Excel文件供PhpSpreadsheet下载

这是我的代码：

    require 'vendor/autoload.php';

    use PhpOffice\PhpSpreadsheet\Spreadsheet;
    use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

    $spreadsheet = new Spreadsheet();
    $sheet = $spreadsheet->getActiveSheet();
    $sheet->setCellValue('A1', 'Hello World !');

    $writer = new Xlsx($spreadsheet);
    $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');

    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment; filename="hello_world.xlsx"');
    $writer->save("php://output");
