Writes selected features of the incoming network to a data table.

A one value column table represents all values in own column. It also contains a feature type column (e.g. string, float, ...) and a feature name column. Example of a one value column table:

Feature target	Graph id	Edge id	Node id	Feature name	Feature type	Feature value
graph	ID	?	?	Description	string	Bla bla bla
node	ID	?	Node1	label	string	Label1
edge	ID	Edge1	?	weight	float	1.0
end	ID	Edge1	Node2	is_target	boolean	true

A table with separate value columns contains for each value a separate column. The example table from above would look like the following:

Feature target	Graph id	Edge id	Node id	Description	label	weight	is_target
graph	ID	?	?	Bla bla bla	?	?	?
node	ID	?	Node1	?	Label1	?	?
edge	ID	Edge1	?	?	?	1.0	?
end	ID	Edge1	Node2	?	?	?	is_target
