 public AddressBookDocumentController(){
this.personData = FXCollections.observableArrayList(

            new Person("A","B","W"),
            new Person("HAi","Bye","E")

    );
 }

@Override
public void initialize(URL url, ResourceBundle rb) {

    firstName.setCellValueFactory(new PropertyValueFactory<Person,String>("firstName"));
    lastName.setCellValueFactory(new PropertyValueFactory<Person,String>("lastName"));
    emailId.setCellValueFactory(new PropertyValueFactory<Person,String>("emailId"));
     tableId.setItems(personData);

}    

final ObservableList<Person> personData ;
@FXML TableView<Person> tableId;
@FXML TableColumn<Person, String> firstName;
@FXML TableColumn<Person,String> lastName;
@FXML TableColumn<Person,String>emailId;
@FXML TextField tfName;
@FXML TextField tlName;
@FXML TextField tEmail;


@FXML public void handleButtonSave(){

    tableId.getItems().get(0).setFirstName("JOHN"); //HERE CHANGES SHOULD REFLECT BUT IT's NOT HAPPENING 
}
}

Thanks, pavan.

Have you tried to follow the official doc ? docs.oracle.com/javafx/2/ui_controls/table-view.htm There is a difference between "ask for help with your code" and "ask for do your job" — Roberto

i followed this link "docs.oracle.com/javafx/2/ui_controls/table-view.htm" only. i am able to add data to tableview through ObservableList. But i want to update particular cell value through button click event. i tried this also through tableview.getItems().get(0).setFirstName("JOHN"); . But changes are not reflecting. — pavankumar

Ok, in such case, It would help post your code or a fragment that show how are you doing. BTW, have you tried to update the ObservableList ? — Roberto

Add the following JavaFX specific getters to your Person class and then try again:

public SimpleStringProperty firstNameProperty(){
    return firstName;
}

public SimpleStringProperty lastNameProperty(){
    return lastName;
}

public SimpleStringProperty emailidProperty(){
    return emailid;
}

 private final ObservableList<Person> data =
    FXCollections.observableArrayList(
        new Person("", "Smith", ""),

    );



TableColumn col1= new TableColumn("Column1");
    firstNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("Column1"));

TableColumn col2= new TableColumn("Column2");
    lastNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("Column2"));

TableColumn col3= new TableColumn("Column3");
    lastNameCol.setCellValueFactory(
            new PropertyValueFactory<Person, String>("Column3"));

 table.setItems(data);
     table.getColumns().addAll(col1, col2, col3);
