I guess you mean editable_cells.c. I'm attaching a Python version of
this code.
The problem is that there seems to be a bug in it, and the same bug
exists in the C version as well. The bug is that when you remove a row
with the Remove Item button, the item is not properly deleted - the
Number column is deleted, but Product column is not. Its most obvious
when you try to delete the last row.
I'm using gtk+-1.3.12 on Debian unstable.
