Extract Table Spec
Node extracting the meta information from the input table (column
names, types, etc.) The meta information is referred to as the
table data specification and contains information such as column
names, types, domain values (list of possible values for
categorical columns) and lower and upper bounds. It also contains
the information which of the columns have a view handler associated
(optional operation). Each column in the input table is represented
as a row in the output. This node can be used in conjunction with
the Insert Column Header node, where the column names are extracted
from the input table, then modified in the workflow and later merged
back into the main table.
