据我所知,排版此表而不使用难以阅读的小字体大小的唯一方法是以横向模式排版。
\documentclass{article}
\usepackage{rotating,booktabs,array,amsmath,amssymb}
\newcolumntype{C}{>{$\displaystyle}c<{$}} % automatic display-style math mode
\begin{document}
\begin{sidewaystable}
\setlength\tabcolsep{0pt} % let LaTeX figure out the amount of intercolunn whitespace
