Tree Learners - columns read from table.

I have a table containing a list of "important" attributes column names (subset of 40 out of original 150 attributes) - how can I feed these into a Tree Ensemble Learners list of attribute columns?

A flow variable containing the list would work - but can't see how to do that - the "Table Column to Variable" seems to create a variable for each row.



Hmm, settings 40 flow variables might be a challenge, though generating them is not that hard with the (not too old) Table Column to Variable node.

Probably filtering the table with the Reference Column Filter might be a better choice.

(Transposing might be needed for one of the proposed solutions.)

OK thanks,

RowID -> Transpose -> Reference Column Filter

Does what I need.
