我怎样才能让tabularx里面的第 6 个问题均匀地分成 2 个，而不超出边界？
（我目前使用的p{0.25cm}p{7cm}不是最佳的，因为我需要手动指定宽度）
子问题（不太重要）：
如何将问题 5 中的 (a) 和 (b) 与问题 6 中的 (a) 对齐？
如何缩进问题 6 中的 i.、ii. 和 iii.，使其与 (a) 和 (b) 不对齐？
请注意，下面的示例可以工作，但样式和格式不是最佳的（我还收到了 2Underfull \hbox和 7 条Overfull \hbox消息）。
另请注意，我对 LaTeX 排版非常陌生（昨天才安装！），如果对代码的整体样式有任何反馈，我将不胜感激

\columnbreak

答案2
类似的解决方案，通过 中的中等大小命令进行了一些改进nccmath，并调整了一些长度。主要区别在于，我没有将tabularxs 嵌套在另一个 中tabularx，而是将 嵌套在一个enumerate（使用 定制的enumitem）中，以便获得（可参考的）自动编号：
\documentclass[12pt]{article}
% Set page margin to 1 inch on all sides

您可以使用下面的代码，其中我已替换了p{7cm}byX列以及所有出现的\textwidthby \linewidth。
\documentclass[12pt]{article}
% Set page margin to 1 inch on all sides
\usepackage[margin=1in]{geometry}

Rewrite the above integral using the orders: & Rewrite the above integral using the orders:\\

&

}\\
\end{tabularx}
\end{enumerate}
\end{document}
或者，您可以使用类似下面的解决方案。我已将内部tabularx环境替换为enumerate环境。为了正确设置它，我还用enumerate更强大的enumitem包替换了包。
\documentclass[12pt]{article}
% Set page margin to 1 inch on all sides
\usepackage[margin=1in]{geometry}

Rewrite the above integral using the orders: & Rewrite the above integral using the orders:\\
\begin{minipage}[t]{\linewidth}
\begin{enumerate}[label={\roman*}.,align=left]
\item $dx\,dy\,dz$
\item $dy\,dx\,dz$
\item Evaluate each of the above 3 integrals using your calculator
\end{enumerate}
\end{minipage}&

\item $dy\,dx\,dz$
\item Evaluate each of the above 3 integrals using your calculator
\end{enumerate}
\end{minipage}
\end{tabularx}
\end{enumerate}
\end{document}
要缩进 i.、ii. ...，您可以将选项添加leftmargin=1.75cm到相应的\begin{enumerate}[label={\roman*}.,align=left]行。
