Summing up a column continously

Hi,
I want to sum up a sorted column continously, like Excel is doing it:
B1 = A1
B2=B1 + A2,
B3=B2 + A3

But I have no clue how to do that although I am not a Knime beginner. Any hints, how to do that?

Hi @knimerin

Looks like you need the Moving Aggregation node (option: Cumulative computation).

Nice! I’ve been using KNIME for 8 or 9 years and have always done this with a Java Snippet - never occured to me you could use this node to do the whole table. Thanks!
