Certainly! If you want to create a JavaFX TableView where each row is automatically numbered, you can achieve this by adding an extra column that displays the row number. Here's a concise example to illustrate how you can do 

import javafx.application.Application;
import javafx.beans.property.SimpleStringProperty;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class AutoNumberedTableRows extends Application {

    public static class Person {
        private final SimpleStringProperty name;
        private final SimpleStringProperty email;

        public Person(String name, String email) {
            this.name = new SimpleStringProperty(name);
            this.email = new SimpleStringProperty(email);
        }

        public String getName() {
            return name.get();
        }

        public String getEmail() {
            return email.get();
        }
    }

    @Override
    public void start(Stage primaryStage) {
        TableView<Person> tableView = new TableView<>();
        ObservableList<Person> data = FXCollections.observableArrayList(
                new Person("John Doe", "john@example.com"),
                new Person("Jane Doe", "jane@example.com")
        );

        // Row number column
        TableColumn<Person, Number> rowNumCol = new TableColumn<>("#");
        rowNumCol.setCellValueFactory(cellData -> 
            new javafx.beans.property.ReadOnlyObjectWrapper<>(tableView.getItems().indexOf(cellData.getValue()) + 1)
        );
        rowNumCol.setSortable(false);

        // Name column
        TableColumn<Person, String> nameCol = new TableColumn<>("Name");
        nameCol.setCellValueFactory(new PropertyValueFactory<>("name"));

        // Email column
        TableColumn>Person, String> emailCol = new TableColumn<>("Email");
        emailCol.setCellValueFactory(new PropertyValueFactory<>("email"));

        tableView.setItems(data);
        tableView.getColumns().addAll(rowNumCol, nameCol, emailCol);

        VBox vbox = new VBox(tableView);
        Scene scene = new Scene(vbox);

        primaryStage.setScene(scene);
        primaryStage.setTitle("Auto Numbered Table Rows");
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Explanation:
Person Class: A simple class to hold the data for each row.
TableView Setup: A TableView is created and populated with sample data.
Row Number Column: A column is added to display the row number. The CellValueFactory uses a ReadOnlyObjectWrapper to calculate the row index.
Other Columns: Additional columns for name and email are added.
Scene and Stage: The TableView is added to a VBox, which is then set as the scene of the stage.
This setup ensures that each row in the TableView is automatically numbered, providing a clear and organized display of your data.
