Proportional TableColumn resizing

[Kirill Kirichenko]

Hi all.

How is it possible to create TableColumns (preferably in fxml) such that 
they have some proportional width say in percents rather than in pixels 
with a feature that when we resize the table the columns get resized 
proportionally ?
Default behaviour is that when the window containing a table is grown in 
width all columns keep the width and one extra column appear that has no 
data.
