hi there,
I'd like to know how to add new column, define a name for attribute (head of the column) and keep empty values in the rows.
The reason is that I need to import an excel sheet in rapidminer, modify it (add columns and empty rows) and then import it in an other process that requires columns with empty values.
thank you in advance for your help
