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'])) {

        // table is built from the array keys (instead of array values) of the
        // #default_value property.
        // @todo D8: Remove this inconsistency.
