无法将数据填充到javafx中的TableView

TableView<YourDataClass> tableView = new TableView<>();
TableColumn<YourDataClass, String> column1 = new TableColumn<>("Column 1");
TableColumn<YourDataClass, String> column2 = new TableColumn<>("Column 2");

tableView.getColumns().addAll(column1, column2);

public class YourDataClass {
    private String property1;
    private String property2;

    public YourDataClass(String property1, String property2) {
        this.property1 = property1;
        this.property2 = property2;
    }

    public String getProperty1() {
        return property1;
    }

    public void setProperty1(String property1) {
        this.property1 = property1;
    }

    public String getProperty2() {
        return property2;
    }

    public void setProperty2(String property2) {
        this.property2 = property2;
    }
}

ObservableList<YourDataClass> data = FXCollections.observableArrayList();
data.add(new YourDataClass("Value 1", "Value 2"));

tableView.setItems(data);

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