Greetings. I'm here because I want to do this and I don't even know how to begin.

I'm doing an application which needs a JTable with data from an existing database. I need the table to periodically (I plan to use a Timer) reflect the changes made to the DB (inserting new rows, deleting or updating existing rows) without making the dirty approach of clearing the whole JTable and refilling it again, which is not nice. I need to just add/modify/delete the needed rows, not the whole table.
