Option to not display rownames in editor

[DillonHammill]

Based on use cases within CytoExploreR, it would be handy to have an option to control whether the rownames are displayed in the editor. Ideally the rownames would be present in the output but just not displayed to the user.

However, I suspect that a feature would only work if row_edit = FALSE - as adding/removing rows would require addition/removal of unique rownames from the original data.
