# Aligning multiple array environment vertically (at the bottom)

I have multiple array environment that I want to allign vertically. Currently it looks like:

With a minimal working example being:

\begin{array}{|c  c|}
\hline A_1^1 & A_1^2 \\
A_2^1 & A_2^2 \\
\hline
\end{array} \,
\begin{array}{|c  c|}
\hline B^1 & B^2 \\
\hline
\end{array}


It alligns them in the center. I want them to align them at the bottom. Can anyone help?

Use \begin{array}[b] in both cases.
