I am sure someone has come across this and there is an easy statement/solution for it (I just am not sure what it is):
When you are putting out an update/upgrade to you plug-in which has additional table columns a previous version did not have, how can you test to see if the new coloumns exist already, and add them only if they do not?
This prevents the user from having to remove the table (and all of their data) and re-install the plug-in with the new coloumn data.
