1.为什么表格宽度会超出整个页面的列宽，如何设置？

2.此外，Texing 还给了我以下信息：

    ./cheatsheet.tex:107: Improper \halign inside $$'s.
    <recently read> \halign 

     l.107  \end{align*}

有人可以帮忙吗：）谢谢

使用alignat*并替换您的构造，正如@David Carlisle 所指出的那样，使用一个简单的\everymath{color{myblue}}构造可以使代码（几乎）正常编译。顺便说一句，您将使用（由选项MidnightBlue定义的颜色之一）获得几乎相同的颜色：svgnamesxcolor

\documentclass[10pt,landscape,a4paper, svgnames, x11names]{article}

\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}
\usepackage[utopia,sfscaled]{mathdesign}
\usepackage{amsmath}

\usepackage{multicol}
\setlength{\columnseprule}{0.5pt}
\usepackage[top=0mm,bottom=1mm,left=1mm,right=1mm]{geometry}
\usepackage{lipsum}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{microtype}
\let\bar\overline
\definecolor{myblue}{cmyk}{1,.72,0,.38}

%\everymath\expandafter{\the\everymath \color{myblue}}
%\everydisplay\expandafter{\the\everydisplay \color{myblue}}

\everymath{\color{MidnightBlue}}
\newcommand{\header}{
\begin{mdframed}[style=header]

Page~\thepage~of~3
\end{mdframed}
}

\makeatletter
\renewcommand{\section}{\@startsection{section}{1}{0mm}%
                            {.2ex}%
                            {.2ex}%x
                            {\sffamily\bfseries}}
\makeatother
\begin{document}

\begin{multicols*}{4}

\begin{alignat*}{2}
f(x)&=u(x)+v(x)&{}\rightarrow f'(x)&=u'(x)+v'(x) \\
f(x)&=\lambda*u(x)&{}\rightarrow f'(x)&=\lambda*u'(x) \\

该错误是由于

\everydisplay\expandafter{\the\everydisplay \color{myblue}}

这不是一个受支持的结构。

所有 LaTeX 对齐所依据的基\halign元如果用作$$显示数学中的第一个项目，则具有特殊的显示数学行为，\align取决于该行为，但如果在数学列表的开头插入颜色特殊，则它会插入到基\halign元之前，即使对齐扩展到

 $$\halign....
