I want to create a measure or calculated column (I don’t know what is needed between these two) that displays me all the values of a given column in a table or other chart. How can I write this function?
I have created this measure
sales = selectcolumns(ART, ART[vend]) but if I try to put this measure in the table, no value is displayed.

How can I fix this?
thanks!

This is because I imported the tables with direct query, but I want to divide certain columns and measures into categories. And the ‘only way to do that, is to create calculated measures or columns and put them in folders/categories.
