What are the potential drawbacks of saving a table as XLSX directly, compared to generating a new XLSX file from the data?

Saving a table as XLSX directly may result in loss of formatting, styling, and data integrity. To ensure that all data, formatting, and styling are preserved, it is recommended to generate a new XLSX file from the data. 

// Create a new XLSX file from the data
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();

// Add data to the sheet
$sheet->setCellValue('A1', 'Hello');
$sheet->setCellValue('B1', 'World');

// Save the XLSX file
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Xlsx($spreadsheet);
$writer->save('new_file.xlsx');
