\begin{equation*}
\left[

\multicolumn{2}{c}{\multirow{2}{*}{$1$}} &
\multicolumn{2}{c}{\multirow{2}{*}{$0$}} &
\multicolumn{2}{c}{\multirow{2}{*}{$0$}} \\
&&&&& \\ \hline
\multicolumn{2}{c}{\multirow{2}{*}{$0$}} & 2 & 3 & \multicolumn{2}{c}{\multirow{2 ...

Yes, I've tried multicolumn together with multirow (multirow 'inside' multicolumn)
I don't want make bigger font size. To example 1: Number 2 takes place of two cells (this is my destination), but when I use \multicolumn{2}{c}{2}, has no effect.

Hi everyone.

I have new question. Sorry, but I haven't code for this problem, my question is general :D.
