title: How can I insert column values in a particular row separately?
body: <p>I have a table with columns {a, b, c} and for row x I want to add a value for a, then a value for b, then a value for c all in separate activities as the user progresses through my app (for another user, values for a, b, and c would be added separately to a row y). How can I do this? </p>
