how to draw this table - latex

Question

I'm trying to draw the table of the image, but I can not find the way to do it with latex.
\begin{tabular}{|C{1cm}|C{1cm}|C{1cm}|C{1cm}|C{1cm}|C{1cm}|C{1cm}}
\hline
Tipo RA & \multicolumn{2}{c|}{Area [m$^2$]}& \multicolumn{2}{c|}{Volumen Semiesferico truncado} \\
1 &&&&&&\\ \hline
2 &&&&&&\\ \hline
3 &&&&&&\\ \hline
4 &&&&&&\\ \hline
5 &&&&&&\\ \hline
6 &&&&&&\\ \hline
7 &&&&&&\\ \hline
\end{tabular}

Answer 1

I'd suggest using booktabs:
\documentclass{article}
\usepackage{booktabs,siunitx,makecell}
\newcommand{\pz}{\phantom{0}}
\sisetup{
group-minimum-digits = 3
}
\begin{document}
\noindent
\begin{tabular}{ l *{6}{c} }
\toprule
& \multicolumn{4}{c}{Area [$m^2$]} & \\
\cmidrule{2-5}
& \multicolumn{2}{c}{Circular} & \multicolumn{2}{c}{El\'{\i}ptica} &
\multicolumn{2}{c}{\smash{\makecell[cb]{Volumen Semiesf\'erico \\ truncado [$m^3$]}}} \\
\cmidrule(lr){2-3} \cmidrule(lr){4-5} \cmidrule(lr){6-7}
Tipo RA & Rango & Promedio & Rango & Promedio & Rango & Promedio \\
\midrule
ALTA & \num{20866}--\num{28983} & \num{24446} & \num{13354}--\num{18549} & \num{15645} & \num{589840}--\num{1201636} & \num{883786} \\
MEDIA & \num{16634}--\num{27254} & \num{20241} & \num{12476}--\num{20440} & \num{15180} & \num{539605}--\num{1131633} & \num{730582} \\
BAJA & \pz\num{3822}--\num{25577} & \num{16097} & \pz\num{3407}--\num{22735} & \num{14307} & \pz\num{75664}--\num{1063784} & \num{647366} \\
\bottomrule
\end{tabular}
\end{document}
In general, there is no need for vertical rules in a tabular, as the columnar display of information supports horizontal separation naturally.

Creating tables directly in LaTeX is not an easy task, I suggest you use tools that allow you to create tables for latex online such as: https://www.tablesgenerator.com/
Please add the following required packages to your document preamble:
\usepackage{multirow,multicol, makecell, booktabs}
\begin{tabular}{*{7}{c}}
\toprule
& \multicolumn{4}{c}{\smash{\makecell[c]{Area [$m^2$]}}}
& \multicolumn{2}{c}{\smash{\makecell[c]{Volumen Semiesférico \\ truncado [$m^3$]}}}\\
\cline{2-5}
& \multicolumn{2}{c}{Circular} & \multicolumn{2}{c}{Eliptica} & \\
\cline{2-7}
Tipo RA & Rango & Promedio & Rango & Promedio & Rango & Promedio \\
\midrule
ALTA & 20866-28983 & 24464 & 20866-28983 & 24464 & 20866-28983 & 24464 \\
MEDIA & 20866-28983 & 24464 & 20866-28983 & 24464 & 20866-28983 & 24464 \\
BAJA & 20866-28983 & 24464 & 20866-28983 & 24464 & 20866-28983 & 24464 \\
\bottomrule
\end{tabular}

Answer 3

Just a no-booktabs sketch, to reproduce your table as similar as possible. Using booktabs is of course recommended for a readability concept that holds everywhere but the first sight on the table would then change very much.
\documentclass{article}
\usepackage{multirow}
\begin{document}
Text
\begin{table}[ht]
{\sffamily%
\begin{tabular}{*{7}{c|}}
% be careful when nesting \multicolumn and \multirow
\cline{2-7}
\multirow{2}{*}{ } & \multicolumn{4}{|c|}{Area [$m^2$]} & \multicolumn{2}{c|}{\multirow{2}{*}{\shortstack[c]{Volumen Semiesf\'erico\\ truncado [$m^3$]}}}\\
\cline{2-5}
& \multicolumn{2}{c|}{Circular} & \multicolumn{2}{c|}{El\'{\i}ptica} & \multicolumn{1}{c}{} & \\
% second part below is standard
\hline
\multicolumn{1}{|c|}{Tipo RA} & Rango & Promedio & Rango & Promedio & Rango & Promedio\\
\hline
\multicolumn{1}{|c|}{ALTA} & 2 - 2 & 3 & 4 - 4 & 5 & 6 - 6 & 7\\
\hline
\multicolumn{1}{|c|}{MEDIA} & 2 - 2 & 3 & 4 - 4 & 5 & 6 - 6 & 7\\
\hline
\multicolumn{1}{|c|}{BAJA} & 2 - 2 & 3 & 4 - 4 & 5 & 6 - 6 & 7\\
\hline
\end{tabular}
}%
\end{table}
Text.
\end{document}
The output of this code is:
Alignments, line breaks and spacing may be considerably improved, also depending on your time and objectives.
