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

& Operation Analysis & 0.27 & & Speech Clarity & 0.23 & \ \\ \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?


\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\multirowand\multicolumn(see e.g. Combining multirow and multicolumn) – dexteritas Jan 13 '18 at 16:48
