如果单元格包含特定符号，请使用 siunitx 格式化单元格

在我之前的问题，大卫·卡莱尔当单元格包含 时，为单元格中的所有文本着色提供了很好的解决方案\*。

我玩了一下这段代码，但如果siunitx使用该包则无法将其包含在内：

\documentclass{article}
\usepackage{color}
\usepackage{array}
\usepackage{tabularx}
\usepackage{siunitx}

{\catcode`\*=\active
\gdef\zz#1{%
\mathcode`\*="8000
\gdef\foo{}%
\def*{\gdef\foo{\color{red}}}%
\setbox0\hbox\bgroup$}
}
\def\zzz{$\egroup\foo{\box0}}

\begin{document}
Not colored here: -12*, But colored within the tabular
\begin{tabular}{ 
>{\zz}l<{\zzz}
>{\zz}c<{\zzz}
>{\zz}r<{\zzz}
}
  1 & 2 & 3 \\
  14* & 5 & 6 \\
  7 & 8* & -9* \\
\end{tabular}
and again not colored here: $-12$.

But not here:
\begin{tabularx}{\linewidth}
    {
    X
    >{\zz}c<{\zzz}
    >{\zz}S[table-format=1.2,input-close-uncertainty=]<{\zzz}
    >{\zz}c<{\zzz}  
    }
Numbers & 1 & 2.00* & 3 \\
\end{tabularx}
\end{document}

您有什么想法吗？如何进行设置siunitx？

\*此外，如果它们能够在着色过程中停留并且不会消失，那就太好了。

答案1

我假设 * 仅用于包含数字的单元格；然后在特殊环境中，任何连贯的减号、数字和句点后跟一个 * 都会以 * 作为前缀，\color{red}并且 * 会被删除。

如果你想保留星号，你可以这样做

\documentclass{article}
\usepackage{color}
\usepackage{array}
\usepackage{tabularx}
\usepackage{siunitx}

\usepackage{xparse,environ}

\newcommand\milasterisk{\makebox[0pt][l]{$^*$}}

随着xparse2019-05-03 的发布，具有类似于的内置功能environ，代码变为
