TableView paginator での使用方法.?.この例では... 

public class SampleController implements Initializable {

    @FXML private TableView<Student> table;
    @FXML private TableColumn<Student, Integer> id;
    @FXML private TableColumn<Student, String> name;
    @FXML private ObservableList<Student> list = FXCollections.observableArrayList();
    //  @FXML private Pagination pagination;
    // 
    private StudentSQL ssql = new StudentSQL();
    private Stage stage = new Stage();
    private String row;

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        id.setCellValueFactory(new PropertyValueFactory<Student, Integer>("id"));
        name.setCellValueFactory(new PropertyValueFactory<Student, String>("name"));
        list = ssql.students();
        table.setItems(list);
    }
}

TableView を Pagination コントロールと統合するためのサンプル コードを次に示します。

このコードは、 PaginatedTableViewコントロールに対する Oracle JavaFX フォーラムのリクエストに対する Shakir Quasaroff の回答から来ています。サンプル コードは、元の質問のような Java コード/FXML ハイブリッドではなく、純粋な Java ソリューションです。
