A table with some cells selected

Question

I have an assignment at university and I have to write some documents written by hand into a TeX document. I'm facing a problem with the following table:

Is it possible to achieve a result similar to the picture above using TeX? I'm not asking for a provided working solution, I'm wondering if I should do it with a photo editor or not (and in this case a little hint would be helpful).

Examples for cell highlighting can be found here, here and here. This shows an example for the beamer class, but looks more like what you want. — Hackbard_C, Aug 25 '14 at 14:22
Maybe even better: Circle around content of a table: is it possible? — Hackbard_C, Aug 25 '14 at 14:28
Thanks to both of you, some examples in the links provide the code I need! — Mangusto, Aug 25 '14 at 14:42

You can try tikz package and put your table (I use the simple tableau package here) inside a node to make drawing easier. Here is my code:

\documentclass[border=2mm]{standalone}
\usepackage{ytableau,tikz,varwidth}
\usetikzlibrary{calc,shapes}
\begin{document}

\ytableausetup{boxsize=2em}
\begin{tikzpicture}[b/.style={rounded corners,fill=blue!50,opacity=0.5,minimum width=1.2em,minimum height=7.5em}]
\node (n) {\begin{varwidth}{5cm}{
\begin{ytableau}
50 & 0 & 150 & 200 \\
50 & 0 & 200 & 100 \\
100 & 0 & 250 & 200 \\
0 & 0 & 0 & 0 \\
\end{ytableau}}\end{varwidth}};

\node [b] at ([xshift=-1em]n) {};
\node [b,rotate=90] at ([yshift=-3em]n) {};

\end{tikzpicture}
\end{document}

The table now looks like this:

Only with tikz and the fit and matrix libraries. I also used backgrounds library for highlighting in the background (and does not cover the numbers).

\documentclass[border=1mm,tikz]{standalone}
\usetikzlibrary{fit,matrix,backgrounds}
\begin{document}
\begin{tikzpicture}
\matrix[matrix of math nodes,% Not strictly necessary but useful to put math symbols $...$
row sep=-\pgflinewidth,column sep=-\pgflinewidth,% Overlaps borders of the nodes 
nodes={draw,minimum width=2em,minimum height=2em},inner sep=0.5ex] (mymatrix) {
    50  & 0 & 150 & 200 \\
    50  & 0 & 200 & 100 \\
    100 & 0 & 250 & 200 \\
     0  & 0 &  0  &  0  \\
};
\begin{pgfonlayer}{background}
\node[fill=blue!50,opacity=0.5,inner sep=-0.8ex,rounded corners=6pt,fit=(mymatrix-1-2)(mymatrix-4-2)] {};
\node[fill=blue!50,opacity=0.5,inner sep=-1ex,rounded corners=6pt,fit=(mymatrix-4-1)(mymatrix-4-4)] {};
\end{pgfonlayer}
\end{tikzpicture}
\end{document}
