Using ctable package with apa6 class

Question

I'm trying to use ctable since it's much easier to work with than threeparttable and all of its additional packages but I get an error stating that "Command \tnote already defined".

I think it's something to do with the apa6 class but I don't know how to change that.

\documentclass[man]{apa6}
\usepackage{ctable}
\shorttitle{}

\begin{document}

\ctable[
caption = Some caption,
pos = h
]{ccc}{
}{\FL
A & B & C\ML
1 & 2 & 3\NN
4 & 5 & 6\LL
}

\end{document}

Answer 1

As mentioned by Mike in comment, apa6 loads threeparttable which defines \tnote. As such, "undefining" \tnote via

\let\tnote\relax

resolves the conflict between ctable and threeparttable:

\documentclass[jou]{apa6}% http://ctan.org/pkg/apa6
\let\tnote\relax% "Free up" \tnote for use in ctable
\usepackage{ctable}% http://ctan.org/pkg/ctable
\shorttitle{}
\begin{document}
\ctable[
    caption = Some caption,
    pos = h
  ]{ccc}{
  }{\FL
    A & B & C\ML
    1 & 2 & 3\NN
    4 & 5 & 6\LL
  }
\end{document}

Alternatively, use the threeparttable format as suggested by Mike.

Answer 2

Depending on what you're trying to get out of ctable, it might be easiest to stick with threeparttable, since apa6 automatically loads it. Slightly adapted example including a footnote (like what ctable's \tnote would do):

\documentclass[jou]{apa6}
\begin{document}
\begin{table}[htbp]
\caption{A complex table}
\label{tab:ComplexTable}
\begin{tabular}{@{}lrrl@{}} \toprule
Distribution type & \multicolumn{2}{l}{Percentage of} & Total \\
& \multicolumn{2}{l}{targets with} & trials per \\
& \multicolumn{2}{l}{segment in} & participant \\
\cmidrule(r){2-3}
& Onset & Coda & \\
\midrule
Categorical -- onset\tabfnm{a} & 100 & 0 & 196 \\
Probabilistic & 80 & 20 & 200 \\
& 60 & 40 & 160 \\
Categorical -- coda & 0 & 100 & 196 \\
\bottomrule
\end{tabular} \\
\tabfnt{a}{A footnote about categorical -- onset}
\end{table}
\end{document}
