Yes, eager to see where this goes.

I tried to customize your approach to apply to the whole buffer. This
code seems to do a nice job of changing the appearance of the tables
within the buffer, but the extra precision is still maintained on
export.
--8<---------------cut here---------------start------------->8---
#+source: format-table-floats
#+BEGIN_SRC emacs-lisp :results silent :exports none
(add-hook 'org-export-preprocess-final-hook
(lambda ()
(while (re-search-forward
"|?[ ]+\\(-?[0-9]+\\.[0-9]+\\)\\(e-\\)?[ ]+|"
nil t)
(progn
(replace-match (concat
(format "%.4f"
(string-to-number (match-string 1)))
" |"))
(org-table-align)))))
#+END_SRC
--8<---------------cut here---------------end--------------->8---
Can anyone suggest another approach that would change the precision of
floats in all tables in the buffer before export? Perhaps there's a
different hook I should be using for LaTeX export?
Thanks!
