[Tex/LaTex] Remove footnote marks from \listoftables

captionsfloatsfootnotestable of contentstables

I'm using footnote marks in my table captions like this:

\caption{This is title\protect\footnotemark with a foot note}

and then I just use a \footnotetext{Closer explanation...} .

This works just fine, but at the end of my document I want to refer to all my tables with \listoftables. The footmarks remain in titles in the list, but they have different numbers than those in the text – also there are no footnote texts on the page with the list.

Is there a way either to get rid of the footnote marks in the \listoftables or to get the footnote texts appear also on the page with the list?

Thanks for any hints!

You can use the optional argument for \caption:

\caption[text with no footnotes]{text with footnote\footnotemark}

A complete example:

\documentclass{article}
\usepackage[a6paper,paperheight=12cm]{geometry}% just for the example
\usepackage{graphicx}

\begin{document}

\listoffigures
\begin{figure}
\centering
\includegraphics[height=3cm]{example-image-a}
\caption[text with no footnotes]{text with footnote\footnotemark}
\label{fig:test}
 \end{figure}
\footnotetext{test footnote}

\end{document}

enter image description here

However, as egreg has pointed out in a comment, the best option is to try and avoid footnotes in captions for floating objects, since the footnote text and the floating object might result in different pages! This shows this phenomenon (footnote text on page 3, footnote mark on page 4!):

\documentclass{book}
\usepackage[a6paper,paperheight=12cm]{geometry}
\usepackage{graphicx}

\begin{document}

\listoffigures
\chapter{Test}
some text
\begin{figure}
\centering
\includegraphics[height=3cm]{example-image-a}
\caption[text with no footnotes]{text with footnote\footnotemark}
\label{fig:test}
 \end{figure}
\footnotetext{test footnote}

\end{document}

[Tex/LaTex] Making \footnote work in leftbar environment

A slightly longer code, which allows you to only type \footnote. The idea is to make each footnote append \footnotetext{#1} to a token list. This token list is then typeset at the right place. Some trickery is required to get nesting right, as well as hyperref support. Normally, this can be used for other (non-verbatim-ish) environments.

Comments in the code.

\documentclass{article}
\usepackage{etoolbox} % for "\pretocmd".
\makeatletter
%
% User command, see the end of the preamble for use.
% We redefine the environment by adding "\savefoot@begin" at 
% the beginning, and "\savefoot@end" at the end.
%
\newcommand{\DeclareSavefootEnvironment}[1]{%
  \expandafter\pretocmd\csname #1\endcsname
              {\savefoot@begin}{}{\savefoot@patch@error{#1}}%
  \expandafter\pretocmd\csname end#1\endcsname
              {\savefoot@end}{}{\savefoot@patch@error{#1}}%
}
\newcommand{\savefoot@patch@error}[1]{%
  \PackageError{savefoot}{etoolbox failed to patch the environment #1, sorry}{}}
%
% Register allocation.
%
\newcount\c@savefoot@depth
\newtoks\savefoot@toks
%
% "\savefoot@begin" starts an environment which saves footnotes.
% We only want to output footnotes outside any such environment,
% so we count how deep we are in this kind of environment using
% the count "\c@savefoot@depth", which pretends to be a LaTeX
% counter. 
%
% We will store all the "\footnotetext" into the toks 
% "\savefoot@toks". This is initialized _locally_ at the start
% of each "savefoot" environment.
% 
\newcommand{\savefoot@begin}{%
  \advance\c@savefoot@depth by 1\relax  
  \savefoot@toks={}}
%
% When ending a savefoot environment, we check if it was the 
% outermost one. In that case, "\@secondoftwo", we output the
% "\footnotetext" that we saved, after the end of the group.
% The "\endgroup" must be explicitly there; this is the case
% because of how "\end{...}" works in LaTeX2e.
% 
% Since the register "\savefoot@toks" is restored at the end 
% of the group, we need to expand it inside the group, then 
% send "\savefoot@append{<expanded \savefoot@toks>}" after the
% "\endgroup", hence the "\expandafter"s. Same thing when we 
% need to typeset.
% 
\newcommand{\savefoot@end}{%
  \ifnum\c@savefoot@depth>\@ne
  \expandafter\@firstoftwo
  \else
  \expandafter\@secondoftwo
  \fi
  {% Nested, don't output, save to the level above.
    \expandafter\do@after@explicit@endgroup\expandafter{%
      \expandafter\savefoot@append\expandafter{\the\savefoot@toks}}%
  }%
  {% Outside, output.
    \expandafter\do@after@explicit@endgroup\expandafter{%
      \the\savefoot@toks}%
  }%
}
%
% Appending to a toks is standard.
%
\newcommand{\savefoot@append}[1]{%
  \savefoot@toks\expandafter{\the\savefoot@toks#1}}%
%
% To put after "\endgroup", we need delimited parameters,
% hence the "\def". We first check that the command is new,
% just in case.
% 
\newcommand{\do@after@explicit@endgroup}{}
\def\do@after@explicit@endgroup#1#2\endgroup{#2\endgroup#1}
%
% Now the footnote command. We save the old definition, 
% used in the case where we are outside any savefoot
% environment. If we are inside a savefoot environment,
% place the "\footnotemark", and append 
% 
%    \savefoot@setcounter{<explicit number>}\footnotetext{<text>}
% 
% to our register. This will be typeset at the end. We cannot
% just do "\footnotetext[<explicit number>]{<text>}", because
% the hyperref package does not like that.
% 
\let\savefoot@old@footnote\footnote
\renewcommand{\footnote}[1]{%
  \ifnum\c@savefoot@depth>\z@
  \expandafter\@firstoftwo
  \else
  \expandafter\@secondoftwo
  \fi
  {% Inside a leftbar, save the text in the relevant toks.
    \footnotemark
    \savefoot@toks=\expandafter{%
      \the\expandafter\savefoot@toks
      \expandafter\savefoot@setcounter\expandafter{\the\c@footnote}%
      \footnotetext{#1}%

  }%
  {% Don't save, just typeset.
    \savefoot@old@footnote{#1}%
  }%
}
%
% When not using hyperref, just give the counter "footnote" 
% the right value (in that case, "\savefoot@hhyperref@support{#1}"
% will be defined to do nothing).
% 
\newcommand{\savefoot@setcounter}[1]{%
  \setcounter{footnote}{#1}%
  \savefoot@hyperref@support{#1}%
}
% 
% Getting "\footnotetext" and "\footnotemark" to work with hyperref

% sight it seems ok.

\usepackage{framed}

\DeclareSavefootEnvironment{leftbar}

\begin{document}

Some text,\footnote{With a normal footnote.} in which 
footnotes are preserved.\footnote{Even when you put several 
  in a row.}\footnote{Like this.}

\begin{leftbar}
  Also true for the leftbar environment.\footnote{The relevant 
    commands are placed after the end of the environment.} 
  \begin{leftbar}
    And we check that nesting works.\footnote{That was the tricky part\ldots}
  \end{leftbar}
  Maybe it breaks after nesting?\footnote{Let's see.}
\end{leftbar} 

More footnotes.\footnote{Like this.}\footnote{And that.}

\begin{leftbar}
  And another leftbar environment to be sure.\footnote{Does it 
    work? I'll see soon, when I compile.}
\end{leftbar}

[Tex/LaTex] footnote in a tcolorbox environment

If I understand your question correctly, you want to refer to the same footnote from multiple colorboxes. The footnote should furthermore appear at the bottom of a page, not in a colorbox.

The code below provides the answer. Apparently, all you need is footnote labeling because footnotes in tcolorboxes make use of different counters and use letters, which turns out to be very convenient.

\documentclass{article}
\usepackage[paperheight=3in,paperwidth=5in]{geometry}
\usepackage{tcolorbox}

\begin{document}

% The footnote is placed on the page where you place this:
My global footnote is defined here\footnote{\label{name}This is my global footnote.}
% The label is required to refer to the footnote.


\begin{tcolorbox}
 % Refer to the same footnote as follows:
 Second reference to global footnote\footnotemark[\ref{name}]
  \begin{tcolorbox}
    % It's still possible to use local footnotes, which by default (and rather conveniently) uses letters in the tcolorbox environment and has its own counter:
  A local footnote\footnote{This is a local footnote}

  Third reference to global footnote\footnotemark[\ref{name}]

  % Another local footnote, not disturbed by the counter of the global footnote:
  A local footnote\footnote{This is my second local footnote}
 \end{tcolorbox}
\end{tcolorbox}

\end{document}

If you do not want the reference to the global footnote to appear where it's defined, then replace \footnote{\label{... for \addtocounter{footnote}{1}\footnotetext{\label{....
