How to insert a footnote in table / tabular environment?

Question

I am trying to insert a footnote to my document. However, the footnote is on the next page. Furthermore, the numeration of the footnote is wrong as well. Specifically, I have the my table set as a tabular inside a center environment to keep the table in-place within my text.

Does anyone know, how to fix this?

\usepackage{tablefootnote}

\begin{document}

\begin{center}\begin{tabular}{rclcrcl}
   $N_V$ & = & Dimension des Eigenvektors $V$  &$\qquad$& $ V\textsubscript{k}$ &=& kter Eigenvektor der Korrelationsmatrix\\
   $p_{sub}$ & = & Signal-Unterraum  &  $\qquad$      &  $e(f)$  &=& komplexe Exponentialfunktion\tablefootnote{Dieser Term wird benötigt, um eine Fourier-Transformation mit dem Term $V\textsubscript{k}\textsuperscript{H} * e(f)$ zu ermöglichen.}\\
\end{tabular}\end{center}

\end{document}

Answer 1

tablefootnote explicitly states in the documentation that it

... provides the command \tablefootnote to be used in a table or sidewaystable environment ...

Since you've set your tabular inside a center environment, the "delayed" printing of the actual footnote doesn't occur the way it should. Also, since center is probably meant as a table-in-place, the following solution should prove sufficient: Add \usepackage{float} to your preamble (if you haven't already) and set the centered tabular inside a \begin{table}[H]...\end{table} construction.

% <your preamble>
\usepackage{float}
\usepackage{tablefootnote}

% <your in-place-table>
\begin{table}[H]
% <tabular with \tablefootnote>
\end{table}
