Explain combining TreeView/TreeTableView and Controller

[NikkyAI]

in my usecase i have nested lists of Entries (like the Person class)
and i want to be able to edit them like the itemviewmodel/withFXproperties

i need to show different editors for the list header and the lists contents and eventually also different types of entries in the list (that all extend a base class)

1. how can i write PersonList.kt to use a treetableview ?
2. how can i open different editors based on type ?
   eg. Employee, CEO, Manager, etc (just to stay with the person analogy)
