JavaFX:在按键事件时获取TableView中的目标行索引

TableView<Person> tableView = new TableView<>();
ObservableList<Person> data = FXCollections.observableArrayList(
        new Person("John", "Doe"),
        new Person("Jane", "Smith"),
        new Person("Bob", "Johnson")
);
TableColumn<Person, String> firstNameCol = new TableColumn<>("First Name");
firstNameCol.setCellValueFactory(new PropertyValueFactory<>("firstName"));
TableColumn<Person, String> lastNameCol = new TableColumn<>("Last Name");
lastNameCol.setCellValueFactory(new PropertyValueFactory<>("lastName"));
tableView.getColumns().addAll(firstNameCol, lastNameCol);
tableView.setItems(data);

tableView.setOnKeyPressed(event -> {
    if (event.getCode() == KeyCode.ENTER) {
        int selectedIndex = tableView.getSelectionModel().getSelectedIndex();
        System.out.println("Selected row index: " + selectedIndex);
    }
});

Scene scene = new Scene(new StackPane(tableView), 400, 300);
primaryStage.setScene(scene);
primaryStage.show();
