First, I want to thank Michael Dunn for his answer to my last
 question!

 A user can reorder the columns of a JTable; and he can change
 their width. Now, I am about to write code to serialize these
 properties into a text format, so that I can read them the
 next time the program is started.

 If something like this has already been done, please let me
 know, so that I can look at the code to see which properties
 needs to be saved and restored, to reestablish all user
 modifications to the table layout.
