I have an error in the method hideColumn

I want to hide several columns of a datatable using a method hideColumn - $$(“artsku”).hideColumn(“country”);. The columns are hiding but an error - hideColumn: invalid ID or already hidden. What am I doing wrong?

I found the error. I tried to hide a column that I didn’t have. I have another question: Can I check the visible column? and depending on this show or hide the column.

Can I check the visible column?
