我想要两个minipages并排的。我可以轻松做到这一点。但是我想将其变成一个命令，并且它们minipages不再对齐，即使代码看起来相同。
出了什么问题？在 MWE 中，我无需命令即可显示我想要的内容，然后尝试将其放入命令中。
\documentclass{article}
\newcommand{\dualminipage}[2][]
{
\begin{minipage}[t][][t]{0.45\linewidth}
#1
\end{minipage}\hfill
\begin{minipage}[t][][t]{0.45\linewidth}
#2
\end{minipage}
}
\begin{document}
% Firstly the minipages put simply.
\begin{minipage}[t][][t]{0.45\linewidth}
This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side.
\end{minipage}\hfill
\begin{minipage}[t][][t]{0.45\linewidth}
This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side.
\end{minipage}
\vspace{0.5in}
% Now the minipages put into a command
\dualminipage {
This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side. This is the left-hand side.
}
{
This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side. This is the right-hand side.
}
\end{document}
答案1
尝试
\newcommand{\dualminipage}[2]
{
\begin{minipage}[t]{0.45\linewidth}#1\end{minipage}
\hfill
\begin{minipage}[t]{0.45\linewidth}#2\end{minipage}
}
看来您\dualminipage定义中的第二个方框出现了问题。
