JavaFX TableView indexed access or fixed table

I have a TableView in my application used in standard way with CellValueFactory and ObservableList.

However this is not quite enough for me, I explain why: First column a want to have fixed values that stay forever. Three columns follow filled from class

public class ValuesTriplet {

    private StringProperty L1 = new SimpleStringProperty();
    private StringProperty L2 = new SimpleStringProperty();
    private StringProperty L3 = new SimpleStringProperty();

    ...
    // constructor
    // properties setters/getters
}

(This middle part I have working.)
One (last) String column follows.

My problem is that I am reading data from device in following way:
1) the triplets are read and filled to table (the working part) - this also determines rows number
2) single values to last column are read - but only some of rows have them (!). How can I write to existing table without an add() method?
3) goto 1

Or can I have for example single cell factory for every part of these?

In case anything is not clear please ask. Thank you.

A little stand alone test case may make it easier for us to understand your problem.

Is this simply a view update problem? And are the properties that fail to update derived from Observable and part of the observable list and registered as columns via a PropertyValueFactory? If not then the TableView won't know automatically that your model changed. You can force an update explicitly this way: 

    public void updateData() {
        if (tableView.getColumns().size()==0)
            return;
        tableView.getColumns().get(0).setVisible(false);
        tableView.getColumns().get(0).setVisible(true);
    }

I had this issue in a javafx migration for which I had to use the swing table model with a JavaFx table view. Of course the view is not automatically notified about changes to the model. Calling above code after an update to the model updates the table for me.
