* Provides a form element for a table with radios or checkboxes in left column.
*
* Properties:
* - #header: An array of table header labels.
* - #options: An associative array where each key is the value returned when
* a user selects the radio button or checkbox, and each value is the row of
* table data.
* - #empty: The message to display if table does not have any options.
* - #multiple: Set to FALSE to render the table with radios instead checkboxes.
* - #js_select: Set to FALSE if you don't want the select all checkbox added to
* the header.
*
* Other properties of the \Drupal\Core\Render\Element\Table element are also
* available.
*
* Usage example:
* @code
* $header = [
* 'color' => $this->t('Color'),
* 'shape' => $this->t('Shape'),
* ];
*
* $options = [
* 1 => ['color' => 'Red', 'shape' => 'Triangle'],
* 2 => ['color' => 'Green', 'shape' => 'Square'],
* // Prevent users from selecting a row by adding a '#disabled' property set
* // to TRUE.
* 3 => ['color' => 'Blue', 'shape' => 'Hexagon', '#disabled' => TRUE],
* ];
*
