Rendering a basic table with the properties defined, fail with an InvalidComponentException:
Drupal\sdc\Exception\InvalidComponentException: [header] Array value found, but a string or an object is required/n[footer] NULL value found, but a string or an object is required. This may be because the property is empty instead of having data present. If possible fix the source data, use the |default() twig filter, or update the schema to allow multiple types. in Drupal\sdc\Component\ComponentValidator->validateProps() (line 201 of core/modules/sdc/src/Component/ComponentValidator.php).
Add a simple table render-array to a page controller:
namespace Drupal\example\Controller;
use \Drupal\Core\Controller\ControllerBase;
/**
* An example controller.
*/
class ExampleController extends ControllerBase {
/**
* Returns a renderable array for a test page.
*
* return []
*/
public function content() {
$rows = [
['1', '1'],
['2', '2'],
];
$build['table'] = [
'#type' => 'table',
'#caption' => $this->t('PoC'),
'#header' => [
'Col 1',
'Col 2',
],
'#rows' => $rows,
'#empty' => 'No rows found.',
];
return $build;
}
}
I don't know SDC, but changing the header `type: string` to `type: array` and removing the `footer:` "property" from `table.component.yml` let us render the table without issues.
(Could also add `#footer = [];` to the render-array but that do not align with the properties in https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Render%21... )
