Make mark in ctable non italic

Question

Ctable prints the footnote marks in italic font, like in the following example.

How would it be possible to print them in a regular font (both in the table and in the footnote section)?

\ctable[
caption = {Test},
]{ p{0.39\textwidth} X X X}{
  \tnote[1]{Source}
}{
 & Heading1 & Heading 2 & Heading 3\\
 abcd\tmark[1] &  &\\       
}

Answer 1

You can redefine the \tnote and \tmark macros by adding this to your preamble:

\makeatletter

% Redefining \tnote
\renewcommand{\tnote}[2][a]{%
   \ifx\@CTnotespar\@CTtrue%
     \@CTtextsuperscript{\normalfont#1}\,#2
   \else%
     \hbox{\@CTtextsuperscript{\normalfont#1}}&#2\NN
   \fi
}

% Redefining \tmark
\renewcommand{\tmark}[1][a]{%
   \hbox{\textsuperscript{\normalfont#1}}}

\makeatother

The original version contains \textit{#1} instead of #1.

Answer 2

You can write

\tnote[\normalfont1]

and

\tmark[\normalfont1]
