I'd like to creat a table for which I know the number of columns/variable names. However, I don't know how big (how many rows) it needs to be ahead of time and want the number of rows to increase as data is stored in it. Is this possilbe?

Just a comment that I found this pretty slow, in case speed is an issue for you. In my case, it was much faster to accumulate the variables as separate vectors and assemble them into a table after they reached their final sizes.
