如何将关闭按钮添加到JavaFX中除一个选项卡以外的所有选项卡？

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class TabCloseExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        TabPane tabPane = new TabPane();

        // 创建选项卡
        Tab tab1 = createTab("Tab 1");
        Tab tab2 = createTab("Tab 2");
        Tab tab3 = createTab("Tab 3", false); // 这个选项卡不关闭

        // 将选项卡添加到TabPane
        tabPane.getTabs().addAll(tab1, tab2, tab3);

        // 设置关闭策略为ALL_TABS
        tabPane.setTabClosingPolicy(TabPane.TabClosingPolicy.ALL_TABS);

        // 创建场景并显示
        Scene scene = new Scene(tabPane, 400, 300);
        primaryStage.setScene(scene);
        primaryStage.setTitle("Tab Close Example");
        primaryStage.show();
    }

    private Tab createTab(String title, boolean closable) {
        Tab tab = new Tab(title);
        if (closable) {
            // 添加关闭按钮
            Button closeButton = new Button("X");
            closeButton.setOnAction(event -> tabPane.getTabs().remove(tab));
            StackPane stackPane = new StackPane();
            stackPane.getChildren().addAll(tab.getContent(), closeButton);
            tab.setContent(stackPane);
        }
        return tab;
    }

    private Tab createTab(String title) {
        return createTab(title, true);
    }

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