当用户按下 WordPress 中的导出按钮时，我尝试将数据库中的表导出到扩展名为 .CSV 的 Excel 文件。我可以导出表格，但导出时，表格还包含所有 HTML、CSS 和 JavaScript 标签。有人可以检查我的代码并告诉我如何在没有 html 和 CSS 的情况下导出文件吗？我把我的代码放在一个短代码中，然后添加到页面中。 [[我导出的 Excel 文件的屏幕截图] (https://i.stack.imgur.com/QjOhQ.png)] 谢谢 这是我的代码
session_start();

$file_ext_name = $_POST['export_file_type'];
$fileName = "student-sheet";
$student = "SELECT * FROM students";
$query_run = mysqli_query($con, $student);
if(mysqli_num_rows($query_run) > 0)
{
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'ID');

我尝试使用简短的代码将数据库中的表导出到 WordPress 中的 Excel 文件中。我可以导出文件，但是当我打开文件时，文件中还包含页面中的 html、css 和 JavaScript。
