public NewJFrame1() {

    Scene scene = new Scene(new Group());


    final Label label = new Label("Address Book");
    label.setFont(new Font("Arial", 20));

    table.setEditable(true);

    TableColumn firstNameCol = new TableColumn("First Name");

    table.setItems(data);
    table.getColumns().addAll(firstNameCol, lastNameCol, emailCol);

    final TextField addFirstName = new TextField();

    addLastName.setPromptText("Last Name");
    final TextField addEmail = new TextField();
    addEmail.setMaxWidth(emailCol.getPrefWidth());

    addButton.getStyleClass().add("button1");
    addButton.setOnAction(new EventHandler<ActionEvent>() {

                    addFirstName.getText(),

            addFirstName.clear();
            addLastName.clear();
            addEmail.clear();
        }

    hb.getChildren().addAll(addFirstName, addLastName, addEmail, addButton);
    hb.setSpacing(3);

    final VBox vbox = new VBox();
    vbox.setSpacing(5);
    vbox.setPadding(new Insets(10, 0, 0, 10));
    vbox.getChildren().addAll(label, table, hb);

    ((Group) scene.getRoot()).getChildren().addAll(vbox);

    PopupMenu s;
    JFXPanel jf = new JFXPanel();
    jf.add(table);

    jPanel1.add(jf);





}

Answer 1

您不能将TableView 直接添加到JFXPanel。您必须首先使用Scene 填充JFXPanel，然后您可以将TableView 添加到Scene

干杯！
