正如所指出的Christian Hupfer 的回答，该包sgame与 不兼容array。在博弈论中，是否有更宽容的排版收益矩阵的替代方案？
MNWE：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[]{array}
\usepackage{sgame}
\begin{document}
\begin{game}{2}{2}[You][Your partner][Prisoner's Dilemma]
& Talk & Quiet \\
Talk & $-10,-10$ & $-1,-20$ \\
Quiet & $-20,-1$ & $-5,-5$
\end{game}
\end{document}
正如预期的那样，产生了错误：
! Missing # inserted in alignment preamble.
<to be read again>
\cr
l.26 ...{2}[You][Your partner][Prisoner's Dilemma]
?
请注意，我意识到我可以通过多种方式做到这一点，而无需专用包。我问的是是否有人已经发明了我想要的那种轮子。
答案1
你是指这样的事情吗？
