Aggregate columns based on rows category

Is there a node that can as example create sums of a column based on category?

Example Table:

experimentid value
1 2
1 7
1 5
2 324
2 23
3 35

 

the output should contain:

experimentId sum
1 14
2 347
3 35

 

EDIT:

table display does nto actucally seem to work properly...

The GroupBy node can do this. Group by experimentId and aggregate by value with sum as aggregation function.
