Как сделать чекбокс с выбором всех чекбоксов в TableView на JavaFX и FXML?

Мне кажется, я нашёл то, что требуется.


класс Main:

package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import java.io.IOException;
public class Main extends Application{
    @Override
    public void start(Stage primaryStage) throws IOException {
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Tabel Test");
        primaryStage.setScene(new Scene(root, 600, 400));
        primaryStage.show();
    }
    public static void main (String[] args) {
        launch();
    }
}

класс Controller:

package sample;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.CheckBox;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
public class Controller {
    @FXML
    private ResourceBundle resources;
    @FXML
    private URL location;
    @FXML
    private TableView<Names> tabel;
    @FXML
    private TableColumn<Names, Boolean> col1;
    @FXML
    private CheckBox checkBox;
    @FXML
    private TableColumn<Names, String> col2;
    private static boolean chck;
    @FXML
    void checkBoxInitialize(ActionEvent event) {
        chck = checkBox.isSelected() ? true : false;
        for (Names n : data) {
            n.setCheck(chck);
        }
    }
    ObservableList<Names> data = FXCollections.observableArrayList();
    @FXML
    void initialize() {
        col1.setCellValueFactory(new PropertyValueFactory<Names, Boolean>("check"));
        col2.setCellValueFactory(new PropertyValueFactory<Names, String>("name"));
        for (int i = 1; i < 10; i++) {
            data.add(new Names("Name " + i));
        }
        tabel.setItems(data);
    }
}

класс Names:

package sample;
import javafx.scene.control.CheckBox;
public class Names {
    private CheckBox check;
    private String name;
    public CheckBox getCheck() {
        return check;
    }
    public void setCheck(Boolean x) {
        if(x) {
            check.setSelected(true);
        } else {
          check.setSelected(false);
        }
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Names(String name) {
        check = new CheckBox();
        this.name = name;
    }
}
