Collection to String

The node converts one or more collection columns to a string representation. Each individual cell in the collection is converted using its 'toString()' method. Missing cells within collections can optionally be skipped. The separator string between cells can be changed. Individual cells can have prefixes and/or suffixes, and the entire collection can have a prefix and/or suffix. Any of these can include 'special' characters e.g. \t (tab), \n (new line) etc., or be left empty
