There is a widget out there called gtksheet, which is based on the
CList widget, but sounds exactly like what you want.

I'm not sure where you can download it, and if you can't find it
e-mail me at kth@srv.net and I'll send on a copy.
can download it 

Seems to be ok for the short time I've played with, but if anyone
is maintaing it...

A few quick items I spotted in playing around with this
(changed a clist in my program to sheet to play with it)

1. What is the difference between these two functions

        gtk_sheet_set_column_title
        gtk_sheet_column_button_add_label


   The first one is named like what clist uses, but it doesn't
   seem to do anything. Is there a need for two functions?

2. You can't create a cheet with 0 rows. Many errors insue at
   run-time. (Database applications will notice this most I think)

3. If you push the tab after entering something in the right-most
   column, it blanks out your entry and stays where it was.
   It should at least keep the data you entered. Also should
   probibly wrap around to the next column.

4. There is no reverse-tab key that I could find.

5. Is there some way to set justification for one column without
   doing it cell by cell? When the sheet is lengthened, I'd want new
   cells to automatically set the justification.

6. Need to wrap the header files in an '#include "C" {}' wrapper
   for C++. Could this be added to the header files so we don't
   have to remember to? (Yes, the #ifdef...#include "C"...#endif looks
   nasty, but it is nice for us C++ players)

I'll probibly lengthen my wish list more as I play with it.
