You have to put "=9+3" in the table cell just like Excel. The cell will display "12" unless the cell is being edited, in which case you will see the formula "=9+3". Summing values of other cells in the data table works the same way using Excel formulas. "=SUM(B1:B3)" will give you the sum of those three cells (B1, B2, and B3). Hope this helps.
