    @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);
    }
}

推荐答案

你必须使用Pagination 控制和实现一个页面工厂.为每个应该显示的页面调用工厂，您可以使用其参数 pageIndex 向 TableView 提供项目的子列表:

You have to use the Pagination control and implement a page factory. The factory is called for every page that should be displayed and you can use its parameter, the pageIndex, to provide a sublist of items to the TableView:

TableView table = ...

private Node createPage(int pageIndex) {

    int fromIndex = pageIndex * rowsPerPage;
    int toIndex = Math.min(fromIndex + rowsPerPage, data.size());
    table.setItems(FXCollections.observableArrayList(data.subList(fromIndex, toIndex)));

    return new BorderPane(table);
}


@Override
public void start(final Stage stage) throws Exception {

    Pagination pagination = new Pagination((data.size() / rowsPerPage + 1), 0);
    pagination.setPageFactory(this::createPage);
    ...
}
