title: javafx column in tableview auto fit size
body: <p>afaik The TableView in javafx have 2 column resize policies: CONSTRAINED_RESIZE_POLICY and UNCONSTRAINED_RESIZE_POLICY, but I want columns is resized to fit the content of theirs cells
  I think it's a simple problem in other platform (like datagridview in C#) but can not resolve </p>
