how to do row header and editable cell in tableview?

hello, I have some questions about the tableview and tableview model

how do create a row header? In the documentation, it says row header can be set, but it does not say how to do it. (nothing like setrowheader in the api)

also, how to make the cell editable? (like inputfield)

or I just have to make a vector of inputfields for the cell?

thanks alot!!
