The node offers 3 different filtering modes: manually, by name, and by type. - manually you decide which columns to keep and which to leave out, through Add and Remove buttons. - by name you decide which columns to keep based on their name through wildcards and Reg Ex. - by type you decide the columns to keep based on their type, like all Strings or all Integers.
