Footnote in multirow & longtable doesn't print

Question

Why footnote is printed with multirow when I use mpsupertabular environnement and not in the longtable, & how may it run ? Thanks for yours solutions. Here an exemple : the note 3 isn't printed :

% !TEX TS-program = arara   
\documentclass{scrbook}
\usepackage{supertabular}
\usepackage{longtable}  
\usepackage{multirow}

\begin{document}
\begin{center}
\tablehead{\hline}
\tabletail{\hline}
\tablecaption{mpsupertabular}
\begin{mpsupertabular}{|c|c|c|}
\multirow{2}{*}{primo\footnote{note 1}}&1&1\\*\cline{2-3}
&1&2\footnote{note 2}\\ \hline
\end{mpsupertabular}
\end{center}

\begin{longtable}{|c|c|c|}
\hline\endhead
\hline\endfoot
\multirow{2}{*}{secundo\footnote{note 3}}&2&1\\*\cline{2-3}
&2&2\footnote{note 4}\\\hline 
\caption{longtable}
\end{longtable}
\end{document}
% arara: xelatex

Moreover, I use functions such as \gls{} & other own functions which react by inserting footnotes, as well, the use of \footnotemark & \footnotetext is for me impossible.

You could use adjustbox package for get centered tables with footnote and minipage option for this environment

\documentclass{scrbook}
\usepackage{supertabular}
\usepackage{longtable}  
\usepackage{multirow}
\usepackage{adjustbox}

\begin{document}

\begin{center}
\tablehead{\hline}
\tabletail{\hline}
\tablecaption{mpsupertabular}
\begin{mpsupertabular}{|c|c|c|}
\multirow{2}{*}{primo\footnote{note 1}}&1&1\\*\cline{2-3}
&1&2\footnote{note 2}\\ \hline
\end{mpsupertabular}
\end{center}

%\begin{table}
%\begin{minipage}{0.5\textwidth}
%\begin{longtable}{|c|c|c|}
%\hline\endhead
%\hline\endfoot
%\multirow{2}{*}{secundo\footnote{note 3}}&2&1\\*\cline{2-3}
%&2&2\footnote{note 4}\\\hline 
%\caption{longtable}
%\end{longtable}
%\end{minipage}
%\end{table}

\begin{adjustbox}{minipage=0.5\textwidth,margin=0pt \smallskipamount,center}
\begin{longtable}{|c|c|c|}
\hline\endhead
\hline\endfoot
\multirow{2}{*}{secundo\footnote{note 3}}&2&1\\*\cline{2-3}
&2&2\footnote{note 4}\\\hline 
\caption{longtable}
\end{longtable}
\end{adjustbox}
\end{document}

As you can see in the code, there are another way to obtain centered tables with footnote (commented code) without adjustbox package. I suggest you uncomment this code and try run separately each example ...

I see your comment, in that case you can use footnote package and it savebox environment ...

\documentclass{scrbook}
\usepackage{supertabular}
\usepackage{longtable}  
\usepackage{multirow}
\usepackage{footnote}

\begin{document}


\begin{center}
\tablehead{\hline}
\tabletail{\hline}
\tablecaption{mpsupertabular}
\begin{mpsupertabular}{|c|c|c|}
\multirow{2}{*}{primo\footnote{note 1}}&1&1\\*\cline{2-3}
&1&2\footnote{note 2}\\ \hline
\end{mpsupertabular}
\end{center}


\begin{savenotes}
\begin{longtable}{|c|c|c|}
\hline\endhead
%\hline\endfoot
\multirow{2}{*}{secundo\footnote{note 3}}&2&1\\*\cline{2-3}
&2&2\footnote{note 4}\\\hline 
\caption{longtable}
\end{longtable}
\end{savenotes} 

\end{document}

Answer 2

Here's my approach for longtable footnotes which uses mbenotes package.

Note: mbenotes is simply a mbenotes.sty file and you can easily modify the commands from it as per your requirements, which I've done in my solution. Here's the MWE:

% !TEX TS-program = arara

\documentclass{scrbook}
\usepackage{supertabular}
\usepackage{longtable}
\usepackage{multirow}
\usepackage{mbenotes} % to print table notes!
\usepackage{alphalph} % For extended counters!

%Redefined commands from the "mbenotes.sty", as per current requirements!
\renewcommand*{\thetabnote}{\alphalph{\value{tabnote}}}
\renewcommand{\tabnotesize}{\rmfamily\upshape\footnotesize}
\renewcommand{\maketabmark}{{\hbox{\textsuperscript{{\rmfamily\itshape\scriptsize\thetabmark}}}}}
\renewcommand{\tabnoteformat}{\addtolength{\baselineskip}{-1\baselineskip}\addtolength{\parskip}{0.7ex} \leavevmode\llap{\maketabmark}}
% For printing a superscript style comma between two tabnote marks!
\newcommand{\cmsp}{{\hbox{\textsuperscript{\rmfamily\itshape\scriptsize,\,!}}}}
% usage: \tabnotemark[3]\cmsp\tabnotemark[4]

\begin{document}

\begin{center}
\tablehead{\hline}
\tabletail{\hline}
\tablecaption{mpsupertabular}
\begin{mpsupertabular}{|c|c|c|}
\multirow{2}{}{primo\footnote{note 1}}&1&1\\cline{2-3}
&1&2\footnote{note 2}\ \hline
\end{mpsupertabular}
\end{center}

\begin{longtable}{|c|c|c|}
\hline\endhead
%\hline\endfoot
\multirow{2}{}{secundo\tabnotemark[3]}&2&1\\cline{2-3}
&2&2\tabnotemark[4]\ \hline
\caption{longtable}

\tabnotetext[3]{note 3}     % save note 3
\tabnotetext[4]{note 4}     % save note 4
\end{longtable}

\vspace*{-2em}
\noindent\rule{0.4\textwidth}{.4pt}\hfil
\vspace*{-3em}

\thetabnotes[]      % prints table notes!

\end{document}
% arara: xelatex

Output:

Alternatively, if you are OK with all footnotes on a page being printed at the page footer, you could use the footnote package and make use of its \savenotes-\spewnotes combination or the savenotes environment. Here's the alternative solution's MWE:

% !TEX TS-program = arara

\documentclass{scrbook}
\usepackage{supertabular}
\usepackage{longtable}
\usepackage{multirow}
\usepackage{footnote} % to print table notes!
\begin{document}

\savenotes
\begin{longtable}{|c|c|c|}
\hline\endhead
\hline\endfoot
\multirow{2}{}{secundo\footnote{note 3}}&2&1\\cline{2-3}
&2&2\footnote{note 4}\\hline 
\caption{longtable}
\end{longtable}
\spewnotes

\begin{savenotes}
\begin{longtable}{|c|c|c|}
\hline\endhead
\hline\endfoot
\multirow{2}{}{secundo\footnote{note 3}}&2&1\\cline{2-3}
&2&2\footnote{note 4}\\hline 
\caption{longtable}
\end{longtable}
\end{savenotes}

\end{document}
% arara: xelatex

Output:

Hope it helps! :)
