I fiddled with this a little out of curiosity, and I'm not sure it's
going to work with the current #+attr_latex abilities. Someone more
familiar could correct me, though! I think the issue is that the
structure needs to be something like this:[1]

==========

\begin{threeparttable}
\begin{tabular}{c c c c}
    \toprule
    \textbf{1st Column} & \textbf{2nd Colimn} & \textbf{3rd Colimn} &
\textbf{4th Colimn} \\ \midrule
      QWERTY\tnote{1}   &                     &                     &  \\
      ASDFGH\tnote{2}   &                     &                     &
\\ \bottomrule
\end{tabular}
\begin{tablenotes}
\item[1] qwerty; \item[2] asdfgh
\end{tablenotes}
\end{threeparttable}
==========

But Org, I believe, can only wrap stuff in one \begin/end{} pair. So,
naively, I tried:

#+begin_src R :session r :exports results :results output wrap :eval no
library(ascii)

options(asciiType = "org")

data <- data.frame(a = 1:5, b = 6:10, c = 11:15)
cat("#+attr_latex: :environment threeparttable \n")
ascii(data, include.rownames = F, rownames = F, colnames = names(data))

#+end_src

#+RESULTS:
:RESULTS:
#+attr_latex: :environment threeparttable
| a    | b     | c     |
|------+-------+-------|
| 1.00 | 6.00  | 11.00 |
| 2.00 | 7.00  | 12.00 |
| 3.00 | 8.00  | 13.00 |
| 4.00 | 9.00  | 14.00 |
| 5.00 | 10.00 | 15.00 |
:END:

It *sort of* works in that I get LaTeX table syntax wrapped with
\begin/end{threeparttable}, but then I caught that threeparttable is
actually a wrapper around tabular. Not sure how you can currently use
Org to specify two layered wrappers like that? Or you might need
someone to write an equivalent of #+begin/end_center for
threeparttable?

#+begin_threeparttable
table-generating-stuff
#+end_threeparttable

Even more complicate is that tabular ends, then a tablenotes
environment begins/ends, and only *then* does threeparttable end.

Sorry I couldn't be of more help. I wanted to post anyway so that
others might better understand how this is supposed to work. In the
future, I'd highly recommend posting some minimal code so others can
understand. At the very least, post some minimal LaTeX of the sort you
want as a result. Even better would be any Org-specific methods tried.
Otherwise, people scan the email, see threeparttable, have no
reference for it (like me) and probably just delete.

I happen to be on vacation with plenty of time for digging, so I dug
for a bit on this.


Best regards,
John
