Adding a CheckBox column to an existing TableView

I recently wanted to add a CheckBox column to an existing TableView. To study the problem in isolation, I started with Example 13-6 Creating a Table and Adding Data to It. I added a BooleanProperty and accessors to the Person model class, and I added a new TableColumn with a CheckBoxTableCell as the cell factory. As shown in the image, I see a CheckBox on each row. Although all values are true, none are checked; the checkboxes are live, but setActive() is never called. Recent questions on this topic suggest that I'm missing something; I'd welcome any insight.
