[Tex/LaTex] way to make the footnote package work correctly with hyperref

footnoteshyperref

I'm using the footnote package in conjunction with the hyperref package. However, when using more than one footnote per line in an environment (e.g. table, but also other floating environments), the hyperref package creates incorrect links (i.e. links point to the first page in the document).

Why do I want this? Because there is a (Word-)template for my thesis and my latex doc should exactly the same. Using hyperref is not required, but I'd like to work them correctly. Since I use different environments with the savennotes environment, a solution that works with all environments is required.

Please note: I don't want to use special packages like threeparttable or things like \tablefootnote because I need a solution that is applicable to other environments, not only tables. Also, I want to have the footnotes at the bottom of the page like text footnotes. Having them directly beneath the table is not an option (e.g. minipage).

In the MWE below, the last footnote in each row is correctly linked by hyperref, however, the others point to the first page:

\documentclass[12pt,a4paper,twoside,openany,fleqn]{book}

\usepackage{lipsum}

\usepackage{hyperref}

\usepackage{footnote}
\makesavenoteenv{table}

\begin{document}
\chapter{First Chapter}

\lipsum[1-3]

\begin{table}[htp]%
\begin{tabular}{lcr}
    My text\footnote{Incorrect 1}\footnote{Incorrect 2}\footnote{Correct 1} \\
    My text\footnote{Incorrect 3}\footnote{Correct 2} \\
    My text\footnote{Correct 3} \\
\end{tabular}
\caption{Test}
\end{table}

\lipsum[1]

\end{document}

Don't do it. Depending on how your table floats the footnote counter get out of sync and the footnote text can end on other pages:

\documentclass[12pt,a4paper,twoside,openany,fleqn]{book}

\usepackage{lipsum}
\usepackage{footnote}
%\usepackage{hyperref}


\makesavenoteenv{table}

\begin{document}
\chapter{First Chapter}

\lipsum[1-6]abc\\cde\footnote{blub}

\begin{table}[t]%
\begin{tabular}{lcr}
    My text\footnote{Incorrect 1}\footnote{Incorrect 2}\footnote{Correct 1} \\
    My text\footnote{Incorrect 3}\footnote{Correct 2} \\
    My text\footnote{Correct 3} \\
\end{tabular}
\caption{Test}
\end{table}

bc\footnote{bla}
\lipsum[1]

\end{document}

Regarding hyperref: readme.pdf says about footnote:

This package is not supported, you have to disable hyperref’s footnote support by using option ”hyperfootnotes=false”.

Problem A: Solved

This combination of packages:

works well for me (MWE below). It seems to allow any number of footnotes within figures, tables, and equations, without having to manually update the footnote counter.

Problem B: not solved

The only caveat: Problem B is not solved -- footnotetext may still appear on a different page than footnotemark. However, this is a well-known but surprisingly unsolved problem. IMHO it is not worth fixing since it occurs so infrequently, and I'm sure the reader will be able to figure it out ;)

Problem C: Referencing footnotes in equations.

As shown below, you cannot reference footnotes defined within equations, since the \label links to the equation, not the footnote.

It seems strange to me to have footnotes within equations, and some people would agree, so I might reconsider if this is absolutely necessary.

Code

% !TeX TS-program = pdflatex
% !TeX encoding = UTF-8
% !TeX spellcheck = en_US
% !BIB TS-program = bibtex
%LaTeX=>PDF

\documentclass[12pt]{report}

% solution-related packages
\usepackage{hyperref,tablefootnote,footnotehyper}
\hypersetup{colorlinks}

% formatting stuff
\renewcommand{\baselinestretch}{1.24}
\usepackage{amsmath,booktabs,mwe,pdflscape}
\usepackage[margin=3cm]{geometry}
\setlength{\belowcaptionskip}{\abovecaptionskip}

\begin{document}

Reference the labeled footnote in the figure: \ref{fig-note};

\dots and in the table: \ref{tab-note};

\dots but not in the equation: \ref{eqn-note}.

% Problem A1: solved using tablefootnote -> tablefootnote
%             while this is a figure, it still seems to work
  \begin{figure}[htb]
    \centering
    \includegraphics[width=0.3\textwidth]{example-image}
    \caption[123]{Figure caption with notes:
      A\tablefootnote{\label{fig-note}figure note labeled}
      X\tablefootnote{figure note a}
      Y\tablefootnote{figure note b}}
  \end{figure}

% Problem A2: solved using tablefootnote -> tablefootnote
  \begin{table}[htb]
    \centering
    \caption[123]{Table caption with notes:
      A\tablefootnote{\label{tab-note}table note labeled}
      X\tablefootnote{table note a}
      Y\tablefootnote{table note b}}
     \begin{tabular}{cccccc}\toprule
       A & B & C & D & E & E \\\midrule
       1 & 1 & 2 & 3 & 5 & 8 \\\bottomrule
     \end{tabular}
  \end{table}

% Problem A3: solved using footnotehyper -> savenotes
  \begin{savenotes}
  \begin{align}
    A &\stackrel{\footnote{\label{eqn-note}equation note labeled}}{=} B\\
      &\stackrel{\footnote{equation note a}}{=} C\\
      &\stackrel{\footnote{equation note b}}{=} D
  \end{align}
  \end{savenotes}

% Problem B: someone write a damned package for this already
%            we can usually avoid this problem unless
%            the footnotes are right near the page-break like this
\begin{landscape}
  \clearpage
  \begin{table}[htb]
    \begin{tabular}{p{0.95\hsize}}
      \lipsum[1-3]
      \tablefootnote{test 1}
      \tablefootnote{test 2}
      \tablefootnote{test 3}
    \end{tabular}
  \end{table}
  \clearpage
\end{landscape}

\end{document}
