Code

public static function valueCallback(&$element, $input, FormStateInterface $form_state) {
  // If #multiple is FALSE, the regular default value of radio buttons is used.
  if (!empty($element['#tableselect']) && !empty($element['#multiple'])) {
    // Contrary to #type 'checkboxes', the default value of checkboxes in a
    // table is built from the array keys (instead of array values) of the
    // #default_value property.
    // @todo D8: Remove this inconsistency.
    if ($input === FALSE) {
      $element += array('#default_value' => array());
