# Table width wider than textwidth in threeparttable environment

I have a table that is wider than \textwidth. The table also has footnotes, see the following picture:

I put the table in a threeparttable environment, and try to use \makebox command mentioned in this question to center the table horizontally. However, it does not work. Moreover, there is no space between the superscript a and (K$) in the second row. How can I solve this problem? The following is my MWE: \documentclass[a4paper, 10pt]{article} \usepackage{booktabs} \usepackage{caption} \usepackage[flushleft]{threeparttable} \captionsetup{labelsep=period, skip=5pt} \begin{document} \begin{table}[h] \centering \begin{threeparttable} \caption{Optimal results of Example 2} \label{tab: results2} \begin{tabular}{lccccccccc} \toprule Item & ref. 1 & ref. 2 & ref. 3 & ref. 4 & ref. 5 & ref. 6 & ref. 7 & ref. 8 & Our method\\ \midrule Utility (kW) & 2000 & 3800 & 4200 & & & & & & \\ Capital cost\tnote{a} (k\$) & 163.27 & & & & & & & & \\
Total annual cost (k\$) & 2268.59 & & & & - & & & & \\ \bottomrule \end{tabular} \begin{tablenotes} \vspace*{-2pt} \item[a] {\footnotesize Based on the cost parameters from ref. 6.} \vspace*{-2pt} \item[-] {\footnotesize Not reported in literature.} \end{tablenotes} \end{threeparttable} \end{table} \end{document}  ## 2 Answers When reducing the font size to make a wide table "fit" inside the width of the text block, LaTeX doesn't shrink the amount of intercolumn whitspace proportionally. To salvage any chances of having a readable table, it's important to shrink the amount of intercolumn whitespace as well. I suggest you (i) reorganize the table's header to collect the repeated "Ref." and (ii) use a tabular* environment instead of the basic tabular environment. With these two changes made, it's still necessary to use \scriptsize, for a 30% linear reduction of the main font size. The first horizontal line in the screenshot is there to illustrate the width of the textblock. \documentclass[a4paper, 10pt]{article} \usepackage{booktabs} \usepackage{caption} \captionsetup{labelsep=period, skip=5pt} \usepackage[flushleft]{threeparttable} \begin{document} \hrule % just to illustrate width of textblock \begin{table}[h] \scriptsize \setlength\tabcolsep{0pt} % let LaTeX determine whitespace between columns \begin{threeparttable} \caption{Optimal results of Example 2} \label{tab:results2} \begin{tabular*}{\textwidth}{l@{\extracolsep{\fill}}*{9}{c}} \toprule Item & \multicolumn{8}{c}{Ref.} & Our method\\ \cmidrule{2-9} & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8\\ \midrule Utility (kW) & 2000 & 3800.00 & 4200.00 & 4200.00 & 4200.00 & 4200.00& 4200.00 & 4200.00 & 5000.00\\ Capital cost\tnote{a} (k\$) & 163.27 & & & & & & & & \\
Total annual cost (k\) & 2268.59 & & & & -- & & & & \\ \bottomrule \end{tabular*} \begin{tablenotes} \scriptsize \item[a] Based on the cost parameters from ref.~6. \item[--] Not reported in literature. \end{tablenotes} \end{threeparttable} \end{table} \end{document}  If you're willing to allow line breaks in the first column, it's possible to use \footnotesize (for a 20% reduction in font size) instead of \scriptsize. If you choose this method, you could use a tabularx environment (instead of the tabular* environment used above) to simplify getting optimal line breaks in column 1. I would also suggest you contemplate aligning the numeric data in columns 2 thru 10 on their respective decimal markers, in order to improved the table's readability. I would also replace the slightly comical-looking k\ with 10^\textsuperscript{3} \$. \documentclass[a4paper, 10pt]{article} \usepackage{booktabs,tabularx,ragged2e,dcolumn} \newcolumntype{Y}{>{\RaggedRight}X} \newcolumntype{d}[1]{D..{#1}} \usepackage{caption} \captionsetup{labelsep=period, skip=5pt} \usepackage[flushleft]{threeparttable} \newcommand\mc[1]{\multicolumn{1}{@{}c@{}}{#1}} % handy shortcut macro \begin{document} \hrule % just to illustrate width of textblock \begin{table}[h] \footnotesize \setlength\tabcolsep{1.5pt} % let LaTeX determine whitespace between columns \begin{threeparttable} \caption{Optimal results of Example 2} \label{tab:results2} \begin{tabularx}{\textwidth}{@{}Y*{9}{d{4.2}}@{}} \toprule Item & \multicolumn{8}{c}{Ref.} & \mc{Our method}\\ \cmidrule(lr){2-9} & \mc{1} & \mc{2} & \mc{3} & \mc{4} & \mc{5} & \mc{6} & \mc{7} & \mc{8}\\ \midrule Utility (kW) & 2000 & 3800.00 & 4200.00 & 4200.00 & 4200.00 & 4200.00& 4200.00 & 4200.00 & 5000.00\\ Capital cost\tnote{a} (10\textsuperscript{3}\,\$)

• @Nick, sorry for taking so long to answer. I used adjustbox because the table was too wide to fit a page, that's why the fonts got smaller --- and i took that from the answer you linked. Anyway, Mico's answer is much more complete. – henrique Aug 18 '15 at 19:25
