Added code to include one extra column as a row header, but then dropped it in favor of trying out SpreadsheetView from ControlsFX project.
Changes made by NB 7.4 after switching from JDK 7 to JDK 8 EA (b21)
Comment out method: public static void configureRowHeaders( TableView table )
Take advantage of CSS syntax to combine some lines of code
Removed dependency on TableViewUtil
Upgrade to NB 8 (beta) and JDK 8 (ea)
