• Welcome to TeX.SX! Please help us help you by providing a minimal compilable code example (MWE) showing what you've tried so far. Sep 22 '18 at 14:59

I can reproduce it with

\documentclass{article}
\usepackage{amsmath}

\begin{document}


\end{document}


• If you want that the items in the first column are centered with respect to the boxes, then remove [b] in the code for \tempblock. Sep 22 '18 at 15:20
