答案2
具有单一环境的简短代码blockarray
:
\documentclass{article}
\usepackage{blkarray}
\usepackage{amsmath}
\begin{document}
\[ \begin{blockarray}{\{\BAmultirow{2.2cm}c@{\enspace}c\}\BAmultirow{1cm}\{\BAmultirow{2.2cm}c@{\enspace}c\}}
\parbox{1in}{\centering subfields $E$ \\ of $K$ \\ containing $F$} & K & &\centerline{$ \longleftrightarrow $}&
\parbox{1in}{\centering subgroups $H$ \\ of $G$} & 1 & \\
& \vert & & & & \lvert & \\
& E & & & & H & \\
& \vert & & & & \lvert & \\
& F & & & & G &
\end{blockarray} \]%
\end{document}
