# Latex code for table: how to merge rows and colum

I am stuck on writing the latex code of this table. I have tried the following code:

\begin{array}{ | l | l | l | l | l | l | l | }
\hline
\  & \  & \  & \  & \  & \  & \  \\ \hline
\  & \  & \  & \  & \  & \  & \  \\ \hline
\  & \  & \  & \  & \  & \  & \  \\ \hline
USA sample &  &  & Italian sample &  &  & \  \\ \hline
Sign & Capabilities & Magnitude & Sign & Capabilities & Magnitude & \  \\ \hline
Positive & Active Listening & 7.34 & Positive & Fluency of Ideas & 7.93 & \  \\ \hline
& Speech Recognition & 6.97 &  & Operation Analysis & 2.46 & \  \\ \hline
& Deductive Reasoning & 5.72 &  & Problem Sensitivity & 2.95 & \  \\ \hline
& Coordination & 4.41 &  &  &  &  \\ \hline
& System Evaluation & 3.45 &  &  &  &  \\ \hline
Negative & Social Perceptiveness & -9.39 & Negative & Social Perceptiveness & -3.681 &  \\ \hline
& Originality & -6.14 &  & Originality & -3.47 &  \\ \hline
& Speech Clarity & -5.65 &  & Complex Problem Solving & -2.76 &  \\ \hline
& Oral Comprehension & -3.87 &  & Spatial Orientation & -2.5499999999999998 & \  \\ \hline
& Visualization & -3.62 &  & Finger Dexterity & -2.0979999999999999 & \  \\ \hline
& Spatial Orientation & -1.17 &  & \  & \  & \  \\ \hline
Non-significant & Problem Sensitivity & -2.12 & Non-significant & Oral Comprehension & -2.3090000000000002 & \  \\ \hline
& Fluency of Ideas & -1.9 &  & Deductive Reasoning & -2.09 & \  \\ \hline
& Oral Expression & -1.04 &  & Manual Dexterity & -2.08 & \  \\ \hline
& Manual Dexterity & -0.155 &  & Visualization & -1.22 & \  \\ \hline
& Finger Dexterity & 0.95499999999999996 &  & Coordination & -0.4 & \  \\ \hline
& Operation Analysis & 0.27 &  & Speech Clarity & 0.23 & \  \\ \hline
& Complex Problem Solving & 1.84 &  & Oral Expression & 0.245 & \  \\ \hline
&  &  &  & Speech Recognition & 1.37 & \  \\ \hline
&  &  &  & System Evaluation & 1.4 & \  \\ \hline
&  &  &  & Active Listening & 2.3199999999999998 & \  \\ \hline
\end{array}


But it is not correct because it doesn't merge the row(s) as I would like. Can someone provide hints or suggestions?

• Welcome to TeX.SX! A tip: If you indent lines by 4 spaces, they'll be marked as a code sample. You can also highlight the code and click the "code" button (with "{}" on it). – dexteritas Jan 13 '18 at 16:43
• You don't have to sign with your name since it automatically appears in the lower right corner of your post. – dexteritas Jan 13 '18 at 16:43
• Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – dexteritas Jan 13 '18 at 16:45
• You could use \multirow and \multicolumn (see e.g. Combining multirow and multicolumn) – dexteritas Jan 13 '18 at 16:48

Just one version (my view) how to make it a table that even fits into a document:

I've done the following:

• use tabular instead of array (it is not math)
• use booktabs package, remove all vertical rules and most horizontal rules
• remove all unnecessary duplication (incl. extra columns and rows)
• use a more uniform layout by reducing the amount of decimal places to 2 (the S column type can be set up to perform automatic rounding)
• align numbers on decimal markers

Code:

\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage[margin=1cm]{geometry}

\begin{document}
\begin{table}
\centering
\sisetup{table-format=-1.2, round-mode=places}
\begin{tabular}{ l lS lS }
\toprule
Sign & \multicolumn{2}{c}{USA sample} & \multicolumn{2}{c}{Italian sample}\\
\cmidrule(lr){2-3}\cmidrule(lr){4-5}
& Capabilities & {Magnitude} & Capabilities & {Magnitude}\\ \midrule
Positive & Active Listening & 7.34 & Fluency of Ideas & 7.93 \\
& Speech Recognition & 6.97 &  Operation Analysis & 2.46\\
& Deductive Reasoning & 5.72 & Problem Sensitivity & 2.95\\
& Coordination & 4.41 &  &  \\
& System Evaluation & 3.45 &  & \\\addlinespace
Negative & Social Perceptiveness & -9.39 & Social Perceptiveness & -3.681\\

\end{tabular}

• Hey sorry to bother you again! I have a correlation matrix made by 18 element and I need to rotate it in vertical. Do you have any suggestion? I attach the code I used below. Many many thanks. – Roberta Benetti Jan 15 '18 at 10:53
