How can potential issues with tabular data structures in Excel affect the functionality of files generated using PHP?

Potential issues with tabular data structures in Excel, such as inconsistent formatting or missing data, can affect the functionality of files generated using PHP. To solve this, you can use PHP libraries like PHPExcel or PHPSpreadsheet to create Excel files with structured data.

// Example code using PHPSpreadsheet to create an Excel file with tabular data
require 'vendor/autoload.php';

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

// Create a new Spreadsheet object
$spreadsheet = new Spreadsheet();

// Get the active sheet
$sheet = $spreadsheet->getActiveSheet();

// Set data in cells
$sheet->setCellValue('A1', 'Name');
$sheet->setCellValue('B1', 'Age');

$sheet->setCellValue('A2', 'John Doe');
$sheet->setCellValue('B2', 30);

// Save the Excel file
$writer = new Xlsx($spreadsheet);
$writer->save('example.xlsx');
