The design table can include additional columns or rows for information only (notes, intermediate calculations, and so on).
Use the keyword $USER_NOTES in the header of any column or row that you do not want evaluated. You may use as many of these rows or columns as you need. However, you may not include rows or columns with empty headers in the middle of the table.
The column header is not case sensitive.
