Я работаю с JavaFx 2.2. У меня проблема с тем, что я не могу разместить различные компоненты в столбце TableView. Например у меня есть две колонки

1) Ответ

2) AnswerType

Если AnswerType содержит «Multiple Choice», соответствующая ячейка в столбце «Ответ» должна отображать ComboBox, иначе должна отображаться TextField.

У меня есть пример кода ниже, но он отображает либо ComboBox или TextField, но не оба в разных ячейках одного столбца.
