columnsmultirowtables
Most of the places, examples for merging of cells in tables are given. But, I could not find a merging of cells in complicated fashion as shown below. This question may summarize all the possible methods of merging and may serve as the reference for all future questions on merging of cells. Experts can add much more complications if required.
You could use something like the following:
\documentclass{article}
\usepackage{xcolor,colortbl}
\usepackage{enumitem}
\newlist{tabitemize}{itemize}{1}
\setlist[tabitemize]{label=\textbullet,nosep,after=\strut,align=parleft,leftmargin=*,}
\usepackage{calc}
\newcolumntype{P}[1]{>{\raggedright\arraybackslash}p{#1\textwidth-2\tabcolsep-0.6pt}}
\begin{document}
\noindent
\begin{tabular}{|*6{P{0.16}}|}
\hline
\multicolumn{6}{|c|}{\textbf{Work system snapshot}}\\ \hline
\rowcolor{black!25}\multicolumn{3}{|c}{Customers} & \multicolumn{3}{|c|}{Products \& services}\\ \hline
\multicolumn{3}{|P{0.5}}{
\begin{tabitemize}
\item People who have a need for the Smartdevice
\end{tabitemize}} &
\multicolumn{3}{|P{0.5}|}{
\begin{tabitemize}
\item smartdevice in white
\item smartdevice in black
\end{tabitemize}}\\ \hline
\rowcolor{black!25}\multicolumn{6}{|c|}{Major activities or processes}\\ \hline
\multicolumn{3}{|P{0.5}}{
\begin{tabitemize}
\item Procurement
\item inventory management
\item Sales
\end{tabitemize}} &
\multicolumn{3}{P{0.5}|}{
\begin{tabitemize}
\item Manufactoring
\item Billing System
\end{tabitemize}}\\ \hline
\rowcolor{black!25}\multicolumn{2}{|c|}{Participants} & \multicolumn{2}{c|}{Information} & \multicolumn{2}{c|}{Technologies}\\ \hline
\multicolumn{2}{|P{0.33}|}{
\begin{tabitemize}
\item Owner
\item Employees
\item Customers
\item Users
\end{tabitemize}} &
\multicolumn{2}{P{0.33}|}{
\begin{tabitemize}
\item BOM
\item Order database which consist of: sales-, purchase and production orders)
\item Inventory information
\end{tabitemize}} &
\multicolumn{2}{P{0.33}|}{
\begin{tabitemize}
\item ERP system
\item ME \& MII system
\item Web interface
\end{tabitemize}}\\ \hline
\end{tabular}
\end{document}
To decresae vertical spaces above and below the items, you can add something like ,after=\vspace{-\baselineskip},before=\vspace{-0.5\baselineskip} to the \setlist command.
Here are some additional alternative approaches, as you don't really need all the vertical lines to make your table understandable:
\documentclass{article}
\usepackage{booktabs}
\usepackage{enumitem}
\newlist{tabitemize}{itemize}{1}
\setlist[tabitemize]{label=\textbullet,nosep,after=\strut,align=parleft,leftmargin=*,after=\vspace{-\baselineskip},before=\vspace{-0.75\baselineskip}}
\usepackage{calc}
\usepackage{array}
\newcolumntype{P}[1]{>{\raggedright\arraybackslash}p{#1\textwidth-2\tabcolsep}}
\begin{document}
\noindent
\begin{tabular}{*6{P{0.16}}}
\toprule
\multicolumn{6}{c}{\textbf{Work system snapshot}}\\
\midrule
\multicolumn{3}{l}{Customers} & \multicolumn{3}{l}{Products \& services}\\

\multicolumn{3}{P{0.5}}{

\end{tabitemize}}\\

\multicolumn{6}{c}{Major activities or processes}\\

An expl3 implementation.
Items in both csv files are stored in property lists, in the form <row>@<column>, emulating a two-dimensional array. Then a token list variable is built from the data so retrieved, where each cell contains
\__aerys_colortable_color:n { <color> } <item>
where the function is a wrapper around \cellcolor.
\begin{filecontents*}{\jobname-data.csv}

Best Answer
Here is an extended duplication of your table, with the addition of using some
\multirows (from themultirowpackage) just because you asked about some "more elaborate" cell constructs:Some things to note in such
tabularconstructs:*{<num>}{<col spec>}format to duplicate<col spec>a total of<num>times;\multicolumn{<num>}{<col spec>}{<stuff>}, you need to include the "end" vertical rule in<col spec>, since the "begin" vertical rule in a single-ruletabularbelongs to the previous cell (except if you're spanning from the first column);\multirow{<num>}allows for a negative number<num>, which will raise the entries vertically to the middle of<num>rows. If<num>is positive, the entries are dropped. Raising is useful when you have coloured rows, since the colour is set on a row-by-row basis. So, you may want to finish setting the colour of some upper row, and the\multirowan entry "into" it. For this you would need a negative<num>.
