Since 1.4 Java provides a preference API.
More details here http://java.sun.com/j2se/1.4.2/docs/guide/lang/preferences.html You can choose to preserve the column sequence as a preference and use it when you display the table the next time. If your system has multiple users, you can even save the preferences per user.
