tabulated-list-mode inherits from special-mode, so
tabulated-list-mode-map should probably also inherit from
special-mode-map. However, it actually copies special-mode-map in its
definition (https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/emacs-lisp/tabulated-list.el?h=emacs-25.3#n152).
This appears to be the way that the code was written when
tabulated-list-mode was first created. I haven't read the mailing list
archives, so I'm not sure if there was an explanation of why it was
done this way, and there isn't a comment providing details on this
approach. Therefore, I think it should just be making a sparse keymap
here and inheriting from its parent, like most modes do.

Hello -
Here's a tiny patch that changes the call from copy-keymap to make-sparse-keymap.
Thanks,
Alex

Maybe I'm missing something, but I thought the original bug report
said it should inherit from special-mode's keymap? Your patch doesn't
seem to be doing that, or did I miss something?
More generally, I wonder why we don't say in the ELisp manual that a
derived mode should do this with its keymap. Should we?
Thanks.

Nowadays we can inherit from both with something like
(set-keymap-parent map (make-composed-keymap
button-buffer-map
special-mode-map))
