Hi Robert,
PGriffith probably found the solution at the following link on the Internet: https://tips4java.wordpress.com/2008/12/12/table-stop-editing/
PGriffith’s code gets Jide’s table which subclasses Swing’s JTable. You can see the available client properties provided by Swing at this link: http://www.java2s.com/Tutorial/Java/0240__Swing/SwingsClientPropertiesSummaryTable.htm
I don’t think it matters where you put the code. I would put it in the initialize extension function.
