Answer 1

You can use print, println, and foreach for the desired effect:

table foreach { row => row foreach print; println }

You can also use the mkString method on collections, which joins the elements of the list (either with no delimeter, or with an overload that provides a string delimeter):

print(table.map(_.mkString).mkString("\n"))
