How to update the values on a column as the sum of the value from the column and the column before?

Hi everyone,

I want to update the values in a column as the sum of the said values + the value from the column before. Example:

1 2 3 4

0 1 2 3

0 0 1 2

I am trying to turn the table above to the one in below.

1 3 6 10

0 1 3 6

0 0 1 3

Any help is appreciated :slight_smile:
