Tablefootnote in table* environment?

Question

Is it possible to use the tablefootnote package in the table* environment? With the following minimal example, I see the footnotemark in the table, but no footnote text

\documentclass[twocolumn]{article}
\usepackage{tablefootnote}
\begin{document}
\begin{table*}[htb]
\begin{tabular}{ll}
c & a\\
d & b\tablefootnote{This is a test}\\
\end{tabular}
\end{table*}
\end{document}

In the corresponding single column document with the regular table environment, everything works fine:

\documentclass{article}
\usepackage{tablefootnote}
\begin{document}
\begin{table}[htb]
\begin{tabular}{ll}
c & a\\
d & b\tablefootnote{This is a test}\\
\end{tabular}
\end{table}
\end{document}

Answer 1

I would go with footnotemark and \footnotetext mechanism thereby avoiding the necessity of an extra package.

\documentclass[twocolumn]{article}
\usepackage{showframe,lipsum}   %% just for demo
\begin{document}
\lipsum
\begin{table*}%[htb]
\centering
\begin{tabular}{ll}
c & a\\
d & b\footnotemark\\
\end{tabular}
\end{table*}
\footnotetext{This is a test}
\lipsum
\end{document}
