mdframe 大小与表格大小不匹配

mdframe 大小与表格大小不匹配

我在mdframed使用与以下产品组合时遇到了一些问题:tabular。在弄清楚如何让框架的宽度与对象(在我的情况下是表格)的宽度相匹配之后,我使用了一个描述这里,桌子到两边框架之间的空间并不相同。

左侧似乎还有更多空间,大约 30%。以下是 MWE:

\documentclass[a4paper,12pt]{article}
\usepackage{environ}
\usepackage{varwidth}
\usepackage{siunitx}
\usepackage[version=3]{mhchem} % den nemmeste måde at skrive kemiske navne
\usepackage[framemethod=TikZ]{mdframed} % frame i images/figures
\newlength{\MyMdframedWidthTweak}%
\NewEnviron{MyMdframed}[1][]{%
    \setlength{\MyMdframedWidthTweak}{\dimexpr%
        +\mdflength{innerleftmargin}
        +\mdflength{innerrightmargin}
        +\mdflength{leftmargin}
        +\mdflength{rightmargin}
        }%
    \savebox0{%
        \begin{varwidth}{\dimexpr\linewidth-\MyMdframedWidthTweak\relax}%
            \BODY
        \end{varwidth}%
    }%
    \begin{mdframed}[
        linecolor=red,
        linewidth=3pt,
        roundcorner=5pt,
        userdefinedwidth=\dimexpr\wd0+\MyMdframedWidthTweak\relax, 
        #1]
        \usebox0
    \end{mdframed}
}
\begin{document}
\begin{MyMdframed}
\begin{tabular}{l r}
    Trivialnavn & vanillin \\
    Sumformel & \ce{C8H8O3} \\
    Kemisk struktur & \ce{(CH3O)C6H3(OH)CHO} \\

\end{tabular}
\end{MyMdframed}

不是最小,但你明白我的意思。我认为这与表格宽度的计算方式有关,但我不知道如何调整它。当我使用 plaintikz完成所述任务时,我遇到了同样的问题这里

答案1

您必须添加两倍的linewidth框架(这里是 3pt)到userdefinedwidth

userdefinedwidth=\dimexpr\wd0+\MyMdframedWidthTweak+6pt\relax,
