Full Definition of COLUMNIST. : one who writes a newspaper or magazine column.
A column is a piece of journalism where the writer expresses his/her own experiences and opinions, with no pretence to the objectivity normally demanded in the profession. A row is what you get into when a reader vehemently disagrees with your opinion or discounts your claimed experiences. Alternatively, in a table (which I assume you're referring to), rows are horizontal collections of items belonging to a certain category; columns are vertical collections.
