# Numbers in bold inside a table

I have a large table (59 rows and 11 columns) of accuracy results.

Observe that numbers in bold look a lot larger than regular ones. I want something like this:

Here is the code:

\documentclass{article}

\usepackage{tabularx}
\usepackage{booktabs}

\begin{document}
\begin{table}[!htbp]
\scriptsize %\footnotesize
\centering
\caption{Summary of mean accuracy results of the second experiment.}
\hspace*{-1cm}
\begin{tabularx}{1.15\linewidth}{Xlllllllll|l}
\toprule
Datasets  & {\sc Scg-$\kappa$} & {\sc Scg-mi} & {\sc Gasen} & {\sc Mdsq} & {\sc Re} & {\sc OO} & {\sc Kappa} & {\sc CC} & {\sc BB} & {\sc Bagging} \\
\midrule
Anneal & \textbf{83.54} & \textbf{83.54} & 82.78 & 82.78 & 82.78 & 79.11 & 78.33 & 82.34 & 78.35 & 82.78 \\
Audiology & \textbf{47.17} & 47.08 & 46.46 & 46.46 & 46.46 & 46.46 & 46.46 & 46.46 & 46.46 & 46.46 \\
Australian  & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} & \textbf{85.51} \\
\midrule
\textbf{Average ranks} & \textbf{3.14} & \textbf{3.86} & \textbf{4.69} & \textbf{4.94} & \textbf{4.58} & \textbf{6.66} & \textbf{7.03} & \textbf{8.15} & \textbf{6.62} & \textbf{5.34} \\
\bottomrule
\end{tabularx}%
\label{tab5_3}%
\end{table}%

\end{document}


Any suggestions?

• Welcome to TeX.SX! Does this answer help? – Dai Bowen Oct 31 '16 at 21:25
• Thank you @DaiBowen for the fast reply. That answer works fine with "\normal" size, but the results look awful with \footnotesize, \scriptsize. How should I proceed? – Hadjer Oct 31 '16 at 21:37
• they should not look worse at small sizes? – David Carlisle Oct 31 '16 at 21:40
• See also this answer for an application of \fontseries{b}\selectfont for "regular", i.e., non-extended, bold numbers in tables. – Mico Oct 31 '16 at 21:41
• @DavidCarlisle, I meant that the bold numbers look smaller that the regular ones ;) – Hadjer Oct 31 '16 at 22:20

You can use the method outlined in https://tex.stackexchange.com/a/334323/4427

\documentclass{article}

\usepackage{lmodern}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{etoolbox}

\begin{document}

\begin{table}[!htbp]
\small
%\scriptsize
%\footnotesize
\centering

\caption{Summary of mean accuracy results of the second experiment.}
\label{tab5_3}

%% local settings
\sisetup{detect-weight,mode=text}
% for avoiding siunitx using bold extended
\renewrobustcmd{\bfseries}{\fontseries{b}\selectfont}
\renewrobustcmd{\boldmath}{}
% abbreviation
\newrobustcmd{\B}{\bfseries}
% shorten the intercolumn spaces

\begin{tabular}{ @{} l *{10}{S[table-format=2.2]} @{} }

• I got the following error: "xkeyval error detect-weight undefined in families 'key'"; any suggestions – Hadjer Oct 31 '16 at 22:23
• MikTeX 2.8. I compile using pdfTex version 3.14. – Hadjer Oct 31 '16 at 22:29
• @Hadjer What TeX distribution are you using? Version 2 of siunitx was issued in May 2010 and since then it doesn't use xkeyval. You have a very old TeX system. – egreg Oct 31 '16 at 22:30
• @Hadjer - MikTeX2.8 is ancient. Any chance you could update to version 2.9? – Mico Oct 31 '16 at 22:31
• @egreg Thank you for the clarification. I'll do it tonight; you gave me a good reason ;). I guess that the update will solve my problem. – Hadjer Oct 31 '16 at 22:33
