JavaFX:如何在TableColumn中显示String[]的内容？

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {
        TableView<Person> tableView = new TableView<>();
        TableColumn<Person, String[]> column = new TableColumn<>("Skills");

        // 设置CellValueFactory
        column.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Person, String[]>, ObservableValue<String[]>>() {

        tableView.setItems(data);

        primaryStage.setScene(new Scene(tableView, 300, 200));
        primaryStage.show();
    }

    public static class Person {
        private String name;
        private String[] skills;

        public Person(String name, String[] skills) {
            this.name = name;
