Will subcaption and threeparttable live happily ever after? Trouble combining the two

Question

I'm trying to take this MWE table and put it into a subcaption's subtable environment, or, alternatively, use subcaption's subcaption command - see subcaption's manual - to achieve the same end: to have that table twice next to each other.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabulary}
\usepackage{threeparttable}
\usepackage{array}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{caption}
\usepackage[list=true]{subcaption}
%\usepackage[list=true]{subcaption}

\renewcommand{\arraystretch}{1.2}
\sisetup{round-mode=places,round-precision=1, add-decimal-zero=true, add-integer-zero=true, round-integer-to-decimal}

\begin{document}

\begin{table}
\centering
\begin{threeparttable}
\caption{Some long boring caption don't fall asleep 2013}

\begin{tabulary}{\textwidth}{@{}*{1}{l}*{2}{S[table-format=3.2]}@{}}
\toprule
& {incl.\ Ingredients A\tnote{3}} & {excl.\ Ingredients A} \\
\midrule
DDDD & 36.1 & 22.0\\
EEEE & 30.9 & 20.0\\
\bottomrule
\end{tabulary}

\begin{tablenotes}
\item [2] Unweighted Average
\item [] Source: radiowaves from outer space 1999
\end{tablenotes}

\end{threeparttable}
\end{table}

\end{document}

Inter alia I've tried this:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabulary}
\usepackage{threeparttable}
\usepackage{array}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{caption}
\usepackage[list=true]{subcaption}
%\usepackage[list=true]{subcaption}

\renewcommand{\arraystretch}{1.2}
\sisetup{round-mode=places,round-precision=1, add-decimal-zero=true, add-integer-zero=true, round-integer-to-decimal}

\begin{document}

\begin{table}

\begin{subtable}{.5\linewidth}
\centering
\begin{threeparttable}
\caption{Sub_caption A 2013}

\begin{tabulary}{\textwidth}{@{}*{1}{l}*{2}{S[table-format=3.2]}@{}}
\toprule
& {incl.\ Ingredients A\tnote{3}} & {excl.\ Ingredients A} \\
\midrule
DDDD & 36.1 & 22.0\\
EEEE & 30.9 & 20.0\\
\bottomrule
\end{tabulary}

\begin{tablenotes}
\item [2] Unweighted Average
\item [] Source: radiowaves from outer space 1999
\end{tablenotes}

\end{threeparttable}
\end{subtable}


\begin{subtable}{.5\linewidth}
\centering
\begin{threeparttable}
\caption{Sub_caption B 2013}

\begin{tabulary}{\textwidth}{@{}*{1}{l}*{2}{S[table-format=3.2]}@{}}
\toprule
& {incl.\ Ingredients A\tnote{3}} & {excl.\ Ingredients A} \\
\midrule
DDDD & 36.1 & 22.0\\
EEEE & 30.9 & 20.0\\
\bottomrule
\end{tabulary}

\begin{tablenotes}
\item [2] Unweighted Average
\item [] Source: radiowaves from outer space 1999
\end{tablenotes}

\end{threeparttable}
\end{subtable}

\caption{Some long boring caption don't fall asleep 2013}


\end{table}

\end{document}

and this

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{tabulary}
\usepackage{threeparttable}
\usepackage{array}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{caption}
\usepackage[list=true]{subcaption}
%\usepackage[list=true]{subcaption}

\renewcommand{\arraystretch}{1.2}
\sisetup{round-mode=places,round-precision=1, add-decimal-zero=true, add-integer-zero=true, round-integer-to-decimal}

\begin{document}

\begin{table}

\begin{minipage}{.5\linewidth}
\centering
\begin{threeparttable}
\subcaption{Sub_caption A 2013}

\begin{tabulary}{\textwidth}{@{}*{1}{l}*{2}{S[table-format=3.2]}@{}}
\toprule
& {incl.\ Ingredients A\tnote{3}} & {excl.\ Ingredients A} \\
\midrule
DDDD & 36.1 & 22.0\\
EEEE & 30.9 & 20.0\\
\bottomrule
\end{tabulary}

\begin{tablenotes}
\item [2] Unweighted Average
\item [] Source: radiowaves from outer space 1999
\end{tablenotes}

\end{threeparttable}
\end{minipage}


\begin{minipage}{.5\linewidth}
\centering
\begin{threeparttable}
\subcaption{Sub_caption B 2013}

\begin{tabulary}{\textwidth}{@{}*{1}{l}*{2}{S[table-format=3.2]}@{}}
\toprule
& {incl.\ Ingredients A\tnote{3}} & {excl.\ Ingredients A} \\
\midrule

\bottomrule
\end{tabulary}

\begin{tablenotes}
\item [2] Unweighted Average
\item [] Source: radiowaves from outer space 1999
\end{tablenotes}

\end{threeparttable}
\end{minipage}

\caption{Some long boring caption don't fall asleep 2013}


\end{table}

\end{document}

which both return the Package tabulary Warning: No suitable columns! on input line 31. error message. I could post additional failed attempts, but don't think that'd be helpful, would it?

Is there same mistake, or some incompatibility?

Note that I'd like to at least be able to apply the threeparttable with footnotes to all three tables: both the two subtables individually, as well as the "mother table" (whether in the end I'd combine the footnotes (or use any footnotes at all) is another matter...).

Futher, is subcaption capable of doing the list list-of-tables thing also of the subtables layed out neatly as in this subfig example here from here?

Answer 1

tabulary works by changing the width of L, C, R or J columns to achieve the requested total width. You have not supplied any such columns so it can do nothing except complain:

Package tabulary Warning: No suitable columns! 

This is unrelated to any table/subtable environment in which the construct is used.

Then you get $ errors because there is a _ in the caption and the tables come one above the other as they are in separate paragraphs.

Answer 2

OK, so I finally got it working with subfig instead of subcaption.

Apparently, I'd need to install bleeding-edge LaTeX Kernel (thanks David Carlisle, Joseph Wright and Axel Sommerfeldt for noticing and looking into this !)

But after this whole shlep, I remembered the ideas expressed in the booktabs manual (and other common table-style-guides) and found a solution which avoids subfigs & subtables altogether: I "figured" that I'd end up with more lines than text (so-to-speak), and that there's a different way of constructing the table which will reduce the number of lines to the recommended three plus x (\toprule \middlerule \bottomrule and \cmidrule) which just looks SOOO much better.

Bottom line: in TeX there surely will be a way of cookin' up something fancily complicated (and potentially ugly): but simplicity often begets beauty.
