Gridlines on xlsx files help users easily distinguish cells from one another, acting as guides to tell apart between columns and rows. However, for any specific reason, or no reason at all, there is an option to hide gridlines. This spreadsheet tutorial will show how to do that in PhpSpreadsheet.

Requirements:

• Composer
• PHP 7.2 or newer

Step 1.

Setup dependencies.

{
    "require": {
        "phpoffice/phpspreadsheet": "^1.3"
    }
}

composer.json

Step 2.

Install phpspreadsheet.

$ composer install

command line

Step 3.

Create a new PHP file, and start coding.

<?php

// Autoload dependencies
require 'vendor/autoload.php';

// Import the core class of PhpSpreadsheet
use PhpOffice\PhpSpreadsheet\Spreadsheet;

// Import the Xlsx writer class
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

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

// Retrieve the current active worksheet
$sheet = $spreadsheet->getActiveSheet();

// Set cell A1 with the "Hello World !" string value
$sheet->setCellValue('A1', 'Hello World !');

// Hide gridlines
$sheet->setShowGridlines(false);

// Write a new .xlsx file
$writer = new Xlsx($spreadsheet);

// Save the new .xlsx file
$writer->save('create-xlsx-files-with-option-to-hide-the-gridlines.xlsx');

create-xlsx-files-with-option-to-hide-the-gridlines.php

Test.

Run the following codes.

$ php create-xlsx-files-with-option-to-hide-the-gridlines.php

command line

Result.

Open the generated file create-xlsx-files-with-option-to-hide-the-gridlines.xlsx.

// Hide gridlines
$sheet->setShowGridlines(false);

Default.
