in this article, I'll show you how to create a custom controller and render a table that resembles the core backend tables.
Define the route path
mymodule.content.terms:
path: '/mymodule-table'
defaults:
_controller: '\Drupal\mymodule\Controller\MyModuleController::index'
_title: 'MyModule Controller'
requirements:
_permission: 'access content'
Create custom controller
<?php
namespace Drupal\mymodule\Controller;
use Drupal\Core\Controller\ControllerBase;
/**
* Class MyModuleController
* @package Drupal\mymodule\Controller
*/
class MyModuleController extends ControllerBase
{
/**
* @return array
*/
public function index()
{
$header = [
'col1' => t('COL1'),
'col2' => t('COL2'),
];
$rows = [
['test col 1', 'test'],
['test col 1', 'test'],
['test col 1', 'test'],
];
return [
'#type' => 'table',
'#header' => $header,
'#rows' => $rows,
];
}
}
The result looks like this:
Add html to cells:
use Drupal\Core\Render\Markup;
$rows = [
[Markup::create('<strong>test col 1</strong>'),'test'],
[Markup::create('<s>test col 1</s>'), 'test'],
[Markup::create('<div>test col 1</div>'), 'test'],
];
Add Class to cells:
$rows = [
[['data' => 'test col 1', 'class' => 'test-col-1'],'test'],
[['data' => 'test col 2', 'class' => 'test-col-2'],'test'],
[['data' => 'test col 3', 'class' => 'test-col-3'],'test'],
];
Add link to a table field:
use Drupal\Component\Render\FormattableMarkup;
$value = new FormattableMarkup('<a href=":link">More</a>', [':link' => "/mymodule-table"]);
Add rowspan and colspan
$header = [
'col1' => t('COL1'),
'col2' => t('COL2'),
['class' => t('COL3'), 'data' => 'Header 2', 'colspan' => 2],
];
$value = new FormattableMarkup('<a href=":link">More</a>', [':link' => "/mymodule-table"]);
$rows = [
[['data' => 'test col 1', 'class' => 'test-col-1'],'test',['data'=>$value,'colspan' => 2]],
[['data' => 'test col 2', 'class' => 'test-col-2'],'test',['data'=>$value,'colspan' => 2]],
[['data' => 'test col 3', 'class' => 'test-col-3'],'test',['data'=>$value,'colspan' => 2]],
[[ 'data' => 'test col 4','class' => 'test-col-4', 'rowspan' => 2], '1', ['data'=>1, 'colspan' => 2]],
[['data' => '2'], ['data' => '2'],['data' => '2']],
[[ 'data' => 'test col 4','class' => 'test-col-4', 'rowspan' => 2], ['data'=>1, 'rowspan' => 2], 1,1],
[['data' => '2'],['data' => '2']],
];
The result looks like this:
Add Class to row:
$row = array('data' => 'some data');
$rows[] = array('data' => $row, 'class' => array('my-class','my-class2'));
