As of FOX 1.1.23 there is such functionality in FXTable:

# FXTable has two new API's, getMinRowHeight() and getMinColumnwidth() which 
compute the minimum height or width of a row or column in the table based on 
the contents of the items; this substantially simplifies setting up a 
sensible initial table display.
# FXTableItem's getHeight() and getWidth() now yield sensible values; your 
subclass of FXTableItem should overload them if the size computation needs to 
be different.

Ofcourse you can't use it since FXRuby uses the stable tree...
