Hi Craig
If you have Word 2003, you can select the cells you want to allow to be
edited, and use Tools > Protection to restrict editing, but allow exceptions
for your selected area.
In earlier versions of Word you can only allow or prevent editing by
section. So you could effectively allow editing of certain rows by breaking
up your table and putting continuous breaks between them.
Hope this helps.
