I want to have a table with a caption and some footnotes. I decided to use threeparttable. When I use the code `\tnote{1}` in one of the table rows, it correctly displays a 1. But when I use this code in the caption of the table, it doesn't display a thing. According to [this pdf](http://ctan.mirrorcatalogs.com/macros/latex/contrib/threeparttable/threeparttable.pdf), 

> 
> \tnote commands may be given in the caption too, and they will not
>  appear in the list of tables.
>

Is this simply an unsupported feature, or am I doing something wrong? This is (a slimmed down version of) my table:

```
\begin{table}[h]
    \caption{List of bridges.\tnote{1}}
    \label{tb:listbridges}
    \begin{center}
    \begin{threeparttable}
    \begin{tabular}{llll}
        \toprule
        \textbf{Name} & \textbf{Span (m)} & \textbf{Location} & \textbf{Year} \\ \midrule
        Bridge 1 & 255 & Place 1 & 2010 \\
          \\ \bottomrule
    \end{tabular}
    \begin{tablenotes}\footnotesize
        \item[1] Adapted from data received from ...
    \end{tablenotes}
    \end{threeparttable}
    \end{center}
\end{table}

```
