如何使用列锚定TableView？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        TableView<Person> tableView = new TableView<>();

        TableColumn<Person, String> nameColumn = new TableColumn<>("Name");
        nameColumn.setCellValueFactory(new PropertyValueFactory<>("name"));
        nameColumn.setPrefWidth(100);

        TableColumn<Person, Integer> ageColumn = new TableColumn<>("Age");
        ageColumn.setCellValueFactory(new PropertyValueFactory<>("age"));
        ageColumn.setPrefWidth(50);

        TableColumn<Person, String> emailColumn = new TableColumn<>("Email");
        emailColumn.setCellValueFactory(new PropertyValueFactory<>("email"));
        emailColumn.setPrefWidth(200);

        tableView.getColumns().addAll(nameColumn, ageColumn, emailColumn);

        for (int i = 1; i <= 100; i++) {
            tableView.getItems().add(new Person("Person " + i, i, "person" + i + "@example.com"));
        }

        tableView.setFixedCellSize(25);
        tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

        VBox root = new VBox(tableView);
        Scene scene = new Scene(root, 400, 400);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

class Person {
    private String name;
    private int age;
    private String email;

    public Person(String name, int age, String email) {
        this.name = name;
        this.age = age;
        this.email = email;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getEmail() {
        return email;
    }
}
