看看列两侧的空白。我该如何优化它？对我来说，它看起来太多了！

Answer 1

您设置

\setlength\columnsep{40pt} 

在第 5 行，这样列之间就有 40pt 的空间

Answer 2

您有一个\checkboxeshook允许修改checkboxes环境使用的列表参数的命令：

\documentclass[a4paper, 11pts]{exam}
\usepackage{multicol, setspace}
\usepackage{textcomp, booktabs,colortbl}
\usepackage[table]{xcolor}
\setlength\columnsep{40pt}
\onehalfspacing

\renewcommand\checkboxeshook{\setlength\leftmargin{0cm}}
