如何在JavaFX的TableView中定制setCellValueFactory的功能

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

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

TableView<Person> tableView = new TableView<>();

TableColumn<Person, String> nameColumn = new TableColumn<>("Name");
nameColumn.setCellValueFactory(cellData -> {
    Person person = cellData.getValue();
    return new SimpleStringProperty(person.getName().toUpperCase());
});

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

tableView.getColumns().add(nameColumn);
tableView.getColumns().add(ageColumn);

ObservableList<Person> data = FXCollections.observableArrayList(
    new Person("John", 25),
    new Person("Jane", 30),
    new Person("Bob", 40)
);

tableView.setItems(data);
