apply formula to entire column
I am putting together a spreadsheet using Numbers 09. I can apply a formula to an individual cell. I want to add the revenue in C2 + E2 to give me a sum in F2. What I want to do is apply the formula to all of the cells in Column F. I know there is a way to apply a formula for every cell in Column F as i have done this before. I can't remeber how I did it. Any suggestions?
