# Multi_row and multi_column tables issues

I am trying to make the following table attached to the text and I happened to have some issues.

and MWE:

    \documentclass[11pt]{article}

\textwidth 165mm \textheight 230mm \topmargin -5mm
\oddsidemargin 0mm

\usepackage{textcomp}
\usepackage{siunitx}
\usepackage{booktabs}
\usepackage{makecell, multirow}

\usepackage{multicol}
\setlength{\columnsep}{1cm}

\allowdisplaybreaks
\usepackage{ragged2e}

\usepackage{float}
\usepackage{tabularx}
\usepackage{capt-of}
\usepackage{booktabs}
\usepackage{array}
\usepackage{tabu}
\usepackage{boldline}
\usepackage{ltablex}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}

\begin{document}
\pagestyle{empty}

\begin{table}[htb]
\caption{Computational Results: Case III}
\label{tab: Case III}
\centering
\begin{tabu} to \textwidth {X[m,c]X[m,c]X[m,c]X[m,c]}
\toprule
{\multirow{2}{*}{\makecell{Statistics}
& \multicolumn{2}{c}{\makecell{A}}
& \multicolumn{2}{c}{\makecell{B}}
\cmidrule{2-3}\cmidrule{4-5}
{}& {$P_{1}$} & {$P_{2}$} & {$P_{1}$} & {$P_{2}$}\\
\midrule
\bottomrule
\end{tabu}
\end{table}
\end{document}


• Your multirow macro lacks two closing braces. Try with \multirow{2}{*}{\makecell{statistics}}. Also giving full MWE that can be pasted and compiled as it is (here we have to add \begin{document} and so on) would be appreciated. – sztruks Oct 31 '18 at 7:15
• Well, you give a multirow instruction, and your MWE has only one row… Btw I lost time compiling your MWE, because I forgot \usepackage{tabu} – sztruks Oct 31 '18 at 7:34
• @sztruks I just edited the MWE. It pertains to a long paper so I tried to incorporate a MWE just to let it compile. – B. Bornay Oct 31 '18 at 7:44
• Ok, your preamble is full of errors : you shouldn't load twice the same package (texcomp, url). I will clean it for you, to get rid of all packages not usefull for your MWE. – sztruks Oct 31 '18 at 7:48
• I think you should read something about loading packages, you have much time to save here. One package should be load only once, you can pass multiple options. Othewise you loose time (package is loaded twice or more) and options you bypassed for the first time. I think you should also separate package loading of macro settings. – sztruks Oct 31 '18 at 8:00

OK, this is a MWE that works. I will explain the mistakes below.

\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{tabu}
\usepackage{multirow}
\usepackage{makecell}
\usepackage{booktabs}
\usepackage{boldline}
\usepackage{ltablex}
\newcolumntype{C}[1]{>{\centering\arraybackslash}m{#1}}

\begin{document}

\begin{table}[htb]
\caption{Computational Results: Case III}
\label{tab: Case III}
\centering
\begin{tabu} to \textwidth {X[m,c]X[m,c]X[m,c]X[m,c]X[m,c]}
\firsthline
\multirow{2}{*}{\makecell{Statistics}}
& \multicolumn{2}{c}{\makecell{A}}
& \multicolumn{2}{c}{\makecell{B}}\\
\cmidrule(lr){2-3}\cmidrule(lr){4-5}
{}& {$P_{1}$} & {$P_{2}$} & {$P_{1}$} & {$P_{2}$}\\
\midrule
\bottomrule
\end{tabu}
\end{table}

\end{document}


• You forgot one line break after the B cell
• unwanted bracket before multicolumn and forgot to close multicolumn.
• too few columns declared (four instead of five).
• Thanks! Is it also possible to align the "statistics" in the first column with the \midrule? Now, it is positioned above the midrule. – B. Bornay Oct 31 '18 at 8:03
• Sure. Read this tex.stackexchange.com/questions/316169/… or connected. You can then edit my post to center "statistics". – sztruks Oct 31 '18 at 8:08
• I think the makecell instruction has to be improved to center your "Statistics". – sztruks Oct 31 '18 at 8:22
