I have constructed the following table:
To do so, I used the following code:
begin{equation*}
\begin{array}{c|ccc|c}
& & & & \overline{b} \\ \hline
x_5 & 1 & 0 & 0 & 0 \\
x_6 & 0 & 1 & 0 & 0 \\
x_7 & 0 & 0 & 1 & 1\\ \hline
z & 0 & 0 & 0 & 0
\end{array}
\hspace{2cm}
\begin{array}{|c|}
x_1 \\ \hline
\fbox{$0.5$} \\
0.5 \\
1 \\ \hline
10
\end{array}
\end{equation*}
But I really would like to add some further spacing in the tables, making it look bigger, i.e., make them look like this:
What change would I have to make to my code to get the result I want? Thanks for any help in advance!
UPDATE. I was able to extend my tables further horizantally using the command \arraycolsep = 12pt
. How would one make the lines look darker like in the image I posted? The current state is the following:
