Sorry if I fail to phrase the question clearly. English is not my first langauge. ( I would appreciate if someone can help me phrase the question in a less ackward way) What I want is something pretty simple. I have a table where the first row and the first column are filled, but the rest of the cells are empty. I am looking for a way to add every number in the first column with every number in the first row and fill it in their respective cells. For example, cell C2 should be filled with "= C1+A2". Obviously I could type in the fomular mannualy, but I am sure there is a better way.
