working on specific columns

hey there!

I want to know if its possible to work on specific column and ignore the other one in an operation;
for example I’ve got 30 columns and wanna calclulate the average for first till 20. column…

tanx for any suggestion…

Hi @joan

Well I think there are different ways to do this. I found it fun to create a component where you can choose the first and the last column to filter the data table and do some math on the columns e.g. calculate the mean. See this wf: dynamic_column_filtering.knwf (290.9 KB)
