this might be an easy question, but I still consider myself a beginner in KNIME, decovering all the features.
I am trying to understand how to use Column Filter Usage.
What I want to do: I have a data set with a lot of column, out of which one is a country column. Here I want to filter for country x and kick out all the other rows with the other countries. (in excel, I would filter for all countries except the one I want to keep and delete the rows). Is “column filter” the right node and how do I need to proceed?
Thanks a lot,
