If you prefix the first column of the table so that it is a valid
org-mode table like this:

|Res1| Res2| Total
|3   |  4  | =$1+$2
|4   |  5  |
|4   |  5  |
|4   |  6  |
|4   |  7  |
|4   |  8  |
|4   |  9  |

Then you can just hit C-u C-u C-c C-c on the formula line and it moves
to the bottom and updates the entire table giving you this:

| Res1 | Res2 | Res1 + Res2 |
|    3 |    4 |           7 |
|    4 |    5 |           9 |
|    4 |    5 |           9 |
|    4 |    6 |          10 |
|    4 |    7 |          11 |
|    4 |    8 |          12 |
|    4 |    9 |          13 |
#+TBLFM: $3=$1+$2
