Modify data in table once saved?

We recently switched from ACad to DS and we frequently insert tables in drawing to show term strip connections etc. 
Once we save a drawing with a table in it we cannot go back and modify the table information. Tried EditTable but cannot seem to be able to select a cell. Best I can tell it is saving them as a block. Is there a simple fix? Currently if we need different data we have to delete the original table and recreate with the new data. We have almost 20 people all using DS and this currently id creating a major problem.
