Problem when updating item in a tableview

I am working on a code and I would like to know how I can update the elements of a tableview .

That is, I have my code with a editar method that edits the selected components of that table. For example, I have an element that is called prueba and contains a int with value 6. I edit it and call it pruebaedit , change the value of int to 5 and edit that element in ObservableList .

So far so good, but when I give it to save I edit the list but the old data is still shown in the table.

I would like to update the table and every time you edit an element, update the values of this element in the table and show them updated.

You can try creating a TableView<T> object and pass it as a value to your TableView with data.

For example:

TableView<Producto> table = new TableView<>();
ArrayList<Producto> productos = new ArrayList<>();

//Se agregan elementos a tu TableView
table.getItems().addAll(productos);
table.getColumns().addAll(nombre, clave, tiuni, descrip, exis, precio);

/**
 * Método que actualiza información de TableView
 * @return botón de actualizar
 */
public Button bActualizar() {
    actualizar.setOnAction(new EventHandler<ActionEvent>() { //actualizar es tipo Button
        @Override
        public void handle(ActionEvent event) {
            TableView<Producto> pr = new TableView<>();
            table = pr;  //TableView vacío para que no duplique
            //Llamada al método para mostrar table actualizado
        }
    });
    return actualizar;
}
