Implement AbstractTableModel
You should extend AbstractTableModel, and save a HashMap holding all current values of a chosen column. Now, all you need to do is add a method which would first check if the value is in the HashMap, and if so, delete the row from your data structure. Next, you´ll need to revalidate/repaint your table. There´s a pretty good example in Bruce Eckel´s fine book -
Thinking in Java, which you can download for free, or buy. You should also read the full
JTable API. P.S. There´s no need to repost a question just one hour after first posting it.
