# threeparttable notes layout

I am using threeparttable for adding notes to my table. Here is a minimal working example:

\documentclass[12pt]{memoir}

\usepackage[para,online,flushleft]{threeparttable}

\begin{document}
\par
Lets test the threeparttable package.
\begin{table}[h]
\caption{Some very informative caption}
\begin{center}
\begin{threeparttable}
\begin{tabular}{c c c c}
\toprule
\textbf{1st Column} & \textbf{2nd Colimn} & \textbf{3rd Colimn} & \textbf{4th Colimn} \\ \midrule
QWERTY\tnote{1}   &                     &                     &  \\
ASDFGH\tnote{2}   &                     &                     &  \\ \bottomrule
\end{tabular}
\begin{tablenotes}
\item[1] qwerty; \item[2] asdfgh
\end{tablenotes}
\end{threeparttable}
\end{center}
\label{table:simDisimCoefNewDef}
\end{table}
\end{document}


which produce the following:

So what I need is to set minimum distance between notes on same line like in normal text. Is that possible?

The para setting in threeparttable uses an interesting collection of penalties and glue but I think you just want to change the length indicated (the default is 1em I changed it to 6em here) Unrelated but I also changed [h] to [htp] as using h on its own is asking the float to go to the end of the document.

\documentclass[12pt]{memoir}

\usepackage[para,online,flushleft]{threeparttable}

\makeatletter
\def\TPT@doparanotes{\par
\prevdepth\z@ \TPT@hsize

• I guess the question is how to remove the additional space and use a normal interword space (instead of 6em use 0em, of course). I'd notice also that \centering is to be used instead of center and that the \label should be nearer to the caption (just in case some \refstepcounter comes along). Jun 11 '13 at 23:00
• It works with David code and @egreg advice. Jun 11 '13 at 23:13
• @David Carlisle, could you please explain your code because I noticed different output in some cases, e.g. when putting \textit in \item. What are all this penalties for? Jun 12 '13 at 6:38
• @alchemist_bg it's not my code the definition is just copied from three part table I just changed 1em to 6em I'm not sure why Donald had quite such a complicated collection, but he knows what he's doing:-) basically the idea is to allow extra flexibility between the notes and to encourage line breaking there rather than inside the note if possible.

The environment {NiceTabular} of nicematrix has a built-in command \tabularnote to compose notes after the tabular. This list of notes is composed with the tools of the package enumitem. It's possible to customize with all the keys provided by enumitem. For example, the tokens inserted between two notes (in para mode) may be set with the key itemjoin.

\documentclass[12pt]{memoir}
\usepackage{nicematrix,enumitem}

\begin{document}

\begin{table}[h]

\centering
\NiceMatrixOptions{notes/para}
\begin{NiceTabular}{c c c c}
\toprule
\RowStyle{\bfseries}
1st Column & 2nd Column & 3rd Column & 4th Column \\ \midrule
QWERTY\tabularnote{qwerty}  & & &  \\
ASDFGH\tabularnote{asdefgh} & & &  \\ \bottomrule
\end{NiceTabular}
\label{table:simDisimCoefNewDef}
\end{table}
