Tableview未填充Observablelist

Question

我想用在TextAria中输入的查询结果填充TableView 但是当我想将结果插入TableView时出现错误消息：输入

The method setItems(ObservableList<capture#3-of ?>) in the type TableView<capture#3-of ?> is not applicable for the arguments (ObservableList<ObservableList>)

@FXML
private Button button;

@FXML
private TextArea textAria;

@FXML
private TableView<?> jtable;

@FXML
public void Selection(ActionEvent e) {

    try {
        // declaration of the data that will contain the rows
        ObservableList<ObservableList> data = FXCollections.observableArrayList();
        // get query from the textAria
        String query;
        query = textAria.getText().toString();

        // connect to database
        Connection conn = DriverManager.getConnection(url, user, mdp);
        Statement state = conn.createStatement();
        ResultSet result = state.executeQuery(query);
        ResultSetMetaData resultmeta = result.getMetaData();
        String column;

        for (int i = 0; i < resultmeta.getColumnCount(); i++) {
            // We are using non property style for making dynamic table
            final int j = i;
            TableColumn col = new TableColumn(resultmeta.getColumnName(i + 1));
            col.setCellValueFactory(
                    new Callback<CellDataFeatures<ObservableList, String>, ObservableValue<String>>() {

                        public ObservableValue<String> Call1(CellDataFeatures<ObservableList, String> param) {
                            return new SimpleStringProperty(param.getValue().get(j).toString());
                        }

            jtable.getColumns().addAll(col);
            jtable.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY);

            while (result.next()) {

                // Iterate Row
                ObservableList<String> row = FXCollections.observableArrayList();

                for (i = 1; i <= resultmeta.getColumnCount(); i++) {
                    // Iterate Column
                    row.addAll(result.getString(i));
                    System.out.println("Row  added " + row);
                    data.add(row);

                }

            }

            // FINALLY ADDED TO TableView
            jtable.setItems(data);
        }
    } catch (Exception e2) {
        // TODO: handle exception
        e2.printStackTrace();
    }

}
