Symfony (5) Bundle to represent a HTML Table as Object structure of typical elements like Header, Rows, Cells and the possibility to set Attributes (& classes especially) on all elements in PHP Code.

Helpful especially in combination with DataTables, but completely flexible and not bound to that context. To use in combination with DataTables, set the required classes and require DataTables yourself. NOT included in this bundle! If you'd like to use AJAXified DataTables with Symfony, have a look at: https://github.com/omines/datatables-bundle I didn't need that complexity and missed some flexibility instead, which lead me to this project.

Example (in Symfony Controller)

use JPustkuchen\TableClassBundle\Elements\TableRow;
use JPustkuchen\TableClassBundle\TableFactory;

class TsfAgDefaultController extends AbstractController
{
  public function indexAction(Request $request, TableFactory $tableFactory): Response
  {
        $results = [/* Your database query results or custom array as keyed array with row keys as value keys */
          ['col1' => 'Row 1 Cell 1 Value', 'col2' => 'Row 1 Cell 2 Value'],
          ['col1' => 'Row 2 Cell 1 Value', 'col2' => 'Row 2 Cell 2 Value'],
          // ...
        ];
        
        // TableFactory via dependency injection
        $tableMain = $tableFactory->createTable()
          // Set DataTable classes (optional - just as example)
          ->addClassesFromArray(['ui', 'selectable', 'celled', 'striped', 'stackable', 'table'])
          ->setHeaderFromArray([
            'col1' => 'Col 1 Header Label',
            'col2' => 'Col 2 Header Label',
            'tableActions' => 'Actions Example Row',
          ])->addRowsFromArray($results);
          // Alternatively you could also add rows and cols manually by ->addRow() or ->addColumn().

        // Iterate rows for actions on the data:
        $tableMain->iterateRows(function (TableRow $row, $index) {
          // Add classes based on cell values:
          $cellRow1 = $row->getCellbyKey('row1');
          $cellRow1Value = $cellRow1->getValue();
          if ($y) {
            // Add class 'warning' to row if condition is met
            $row->addClass('warning');
          }
          if ($z) {
            // Add class 'error' to cell if condition is met
            $cellRow1->addClass('error');
          }
          return $row;
        });

        // The contained table.html.twig expects the table array structure in the key 'tabledata':
        return $this->render('table.html.twig', [
          'tabledata' => $tableMain->toArray(),
        ]);
    }
}

Installation

Make sure Composer is installed globally, as explained in the installation chapter of the Composer documentation.

Applications that use Symfony Flex

Open a command console, enter your project directory and execute:

$ composer require jpustkuchen/tableclass-bundle

Applications that don't use Symfony Flex

Step 1: Download the Bundle

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ composer require jpustkuchen/tableclass-bundle

Step 2: Enable the Bundle

Then, enable the bundle by adding it to the list of registered bundles in the config/bundles.php file of your project:

// config/bundles.php

return [
    // ...
    <vendor>\<bundle-name>\<bundle-long-name>::class => ['all' => true],
];

Step 2: Use where you need it, for example in a Controller to create and render a table

See example above!

Important: The built-in ->render() function doesn't work yet, if someone knows what's missing in the bundle to make Symfony Twig render the template, please help. Currently the bundles template / view directory isn't considered by Twig as it seems?!

Until that you'll have to copy the table.html.twig template from the bundle into your templates directory and use that to render the table by Twig include!

The contained table.html.twig file is highly customizable by using blocks extensively.

OPTIONAL: Use with DataTables.net

Simply require datatables.net, for example by:

npm install datatables.net

And require it in your app.js, for example like this:

const dt = require('datatables.net');
window.$.DataTable = dt;
window.dt = dt;

Then you'll could for example wrap the bundles table.html.twig in a parent twig file containing the DataTables.net initialisation, for example like this (or any other way):

<script>
  $( document ).ready(function() {
    $('#' + '{{id|default('datatable')|escape('html_attr')}}').DataTable({/* Optional datatables.net Options */});
  });
</script>
<div id="{{ id|default('datatable')|escape('html_attr') }}-wrapper" class="datatable-wrapper">
  {% include 'table.html.twig' %}
</div>

In our example we additionally used a table wrapper element, for more flexibility, for example to use scrolling tables, if needed. This part is also optional.
