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.
