You can use multicolumn to draw custom vertical lines.
\begin{equation*}
\renewcommand{\arraystretch}{2}
\begin{array}{cccc}
\hline
\multicolumn{1}{|c}{\fbox{1}} &
\multicolumn{1}{|c}{2} &
\multicolumn{1}{|c}{3} &
\multicolumn{1}{|c|}{4}
\\\hline
&
\multicolumn{1}{|c}{\fbox{2}} &
\multicolumn{1}{|c}{3} &
\multicolumn{1}{|c|}{4}
\\\cline{2-4}
& &
\multicolumn{1}{|c}{\fbox{3}} &
\multicolumn{1}{|c|}{4}
\\\cline{3-4}
& & &
\multicolumn{1}{|c|}{\fbox{4}}
\\\cline{4-4}
\end{array}
\end{equation*}
