Footnote in table

Question

I have some table like the following one and want to write some configuration using ´footnote´.

\begin{table}
  \begin{center}
    \begin{footnotesize}
     \begin{tabular}{|l|l|l|}
     \hline 
     TPA & Components & Cost \\ \hline
      & Total & 56558.4 \\ \hline 
     \end{tabular}
    \end{footnotesize}
    \caption[]{Hardware cost estimation~\footnote{per router}}
    \label{tab:}
  \end{center}
\end{table}

So, I did a method like https://texfaq.org/FAQ-ftncapt. However, I found upper subscript but didn't figure out how to use a footnote in my table. Where is the footnote I wrote? I want to see "per router".

Could you please fix my LaTeX code?

Why not simply saying "Hardware cost estimation (per router)"? — egreg, Nov 21 '11 at 14:58

You might want to use the tablefootnote package (and probably you want to

remove the \begin{footnotesize} \end{footnotesize}, otherwise the table is printed in footnote size;
replace the center-environment by a simple \centering; and
remove the ~ before the \tablefootnote, because the ~ causes a (non-breakable) space before the footnote-mark).

Minimal example:

\documentclass{article}
\usepackage{tablefootnote}
\begin{document}

\begin{table}
  %\begin{center}% replaced by \centering
  \centering
    %\begin{footnotesize}
     \begin{tabular}{|l|l|l|}
     \hline 
     TPA & Components & Cost \\ \hline
      & Total & 56558.4 \\ \hline 
     \end{tabular}
    %\end{footnotesize}
    \caption[Hardware cost estimation]{%
      Hardware cost estimation\tablefootnote{per router}\label{tab:}}
  %\end{center}
\end{table}
\end{document}

Seems that \cite cannot be used within tablefootnote. – xuhdev Jan 22 '18 at 01:05 — xuhdev, Jan 22 '18 at 01:05

You didn't follow the instructions. The footnote appears when you use a minipage:

\documentclass{article}

\begin{document}

\begin{table}
\begin{minipage}{\textwidth}                                                                                         
\begin{center}
\begin{tabular}{|l|l|l|}
\hline 
TPA & Components & Cost \\
\hline
 & Total & 56558.4 \\                                                                                             
\hline 
\end{tabular}
\caption[Hardware cost estimation]{Hardware cost estimation~\footnote{per router}}
\end{center}
\end{minipage}
\end{table}

\end{document}

The result:

The footnotesize environment is not necessary. The label is not mandatory, when you don't need a label you don't need to use it.

As the link you posted already explains: Use the optional argument of caption to provide a version without footnote for the TOC.

However, this show a, not indexing number. – JHL Nov 21 '11 at 15:37
I think that that does not works properly – JHL Nov 21 '11 at 15:38

@JHL: Please always provide some info other than "it does not work properly". Per you other comment, to get minipage footnotes to use numbers use \renewcommand\thempfootnote{\arabic{mpfootnote}}. – Peter Grill Nov 21 '11 at 16:10

Might be better to

place the caption above the table
use table notes, to place comments under the table. Note: table notes are not the same as footnotes. Footnotes and floating objects does not mix well.
