Project overview 

The downloadable zip file contains an eclipse project which has a MainFrame class for GUI. By modifying the size of the colums and doing a rerun will create a new Table which will have the saved preferences from the last run.

To save the preferences click the save button or the save menu item. The next load will have the changes reflected. Unzip the downloadable and load in the eclipse project. Make a run configuration for MainFrame class and you are all set.
