Table with cell Inside cell (upper corner) and side annotations

Question

I would like to create a table or array with the layout in the figure below, ideally with the nicematrix package wich allows the marginal annotations.

I've read the package documentation and there is maybe a couple of solutions to my question one involves tikz and \CodeAfter, the other \newcolumntype{x}{!{\OnlyMainNiceMatrix{\vrule somelength}}},

I don't know enough of tikz, or how to you get the right somelength, Asking because of exhaustion, no more limit breaks :)

Some ugly latex with NiceArray

$\begin{NiceTabular}{| c c| c c| c c | }[columns-width = 0.5cm,
    cell-space-top-limit = 0.15cm, cell-space-bottom-limit= 0.15cm]
 \hline 
 6 &  &  8 &  & 10 & \\ \cline{1-1} \cline{3-3} \cline {5-5}
  & 0 & & 0 & & 150 \\ 
  \hline
  7 &  & 11 &  & 11 & \\  \cline{1-1} \cline{3-3} \cline {5-5}
  & 175 & & 0 & & 0 \\ 
  \hline
  4 & & 5 & & 12 & \\  \cline{1-1} \cline{3-3} \cline {5-5}
  & 25 & & 100 & & 150 \\
  \hline
\end{NiceTabular}$

With NiceTabular

\begin{table} \label{lab}
\centering
\begin{NiceTabular}{@{}Wl{2.5cm}|Wl{0.5cm}Wr{0.5cm}|Wl{0.5cm}Wr{0.5cm}|Wl{0.5cm}Wr{0.5cm}|Wl{2.5cm}l@{}}
\toprule
& \Block{2-2}{A}  & & \Block{2-2}{B} & &\Block{2-2}{C} & &\Block{2- 2}{D}\\
 & & & & & & & &\\
\midrule
\Block{2- 1}{E} & 6 &  &  8 &  & 10 & &  \Block{2- 1}{5}\\
&  & -- & & -- & & 15 & &\\ \hline
\Block{2- 1}{F} & 7 &  & 11 &  & 11 & & \Block{2- 1}{1}\\
& & 175 & & -- & & -- & &\\ \hline
\Block{2- 1}{G} & 4 & & 5 & & 12 & & \Block{2- 1}{2}\\
& & 25 & & 100 & & 5 & &\\ \hline
\Block{2-1}{Demanda} & \Block{2-2}{200}  & & \Block{2-2}{100} & &\Block{2-2}{300} & &\Block{2- 2}{600}\\
 & & & & & & & &\\
\bottomrule
\end{NiceTabular}
\caption{Cap}
\end{table}

It has almost all of the elements, may we wait a little longer for an answer regarding nicematrix? — Evion, Sep 19 '20 at 01:58
It can be done very easily with a basic package like blkarray. — Bernard, Sep 19 '20 at 07:48

You can do that with a simple tabular:

\documentclass{article}
\usepackage{array, bigstrut, hhline}
\newcommand{\emptycells}[1]{\multicolumn{#1}{c|}{}}
\newcommand{\mc}[2]{\multicolumn{#1}{c}{#2}}
\begin{document}
{\setlength{\bigstrutjot}{0.8ex}
\setlength{\extrarowheight}{2pt}
\begin{tabular}{|*{4}{p{7mm}| >{\centering\arraybackslash}p{3mm}|}l }
\cline{1-8}
  & 2 & & 3 & & 5 & & 6 \ %
 \hhline{|~|-|~|-|~|-|~|-|}
  \multicolumn{2}{|c|}{\bigstrut}& \emptycells{2} & \emptycells{2} & \emptycells{2} & 5 \
 \cline{1-8}
  & 2 & & 1 & & 3 & & 5 \ %
 \hhline{|~|-|~|-|~|-|~|-|}
  \multicolumn{2}{|c|}{\bigstrut} & \multicolumn{2}{l|} {8} & \emptycells{2} & \emptycells{2} & 2 \
 \cline{1-8}
  & 3 & & 8 & & 4 & & 6 \ %
 \hhline{|~|-|~|-|~|-|~|-|}%
\multicolumn{2}{|c|}{\bigstrut}& \emptycells{2} & \emptycells{2} & \emptycells{2} & 15 \
 \cline{1-8}\noalign{\vskip 1ex}
 \mc{2}{12} & \mc{2}{$\times$} & \mc{2}{4} & \mc{2}{6}
 \end{tabular}}
\end{document}
