我有一张表格，其中单元格中的所有数字都对齐到小数点（通过包“siunitx”）。此外，我通过将数字的颜色更改为红色/蓝色来突出显示每列中的两个最低数字。
现在的问题是，有时（例如在第二列），彩色数字未与小数点对齐。我做错了什么？
呈现的表格（在 Overleaf 中）如下所示：
该表的 Latex 源代码如下：

答案1
我不会c对四个数字数据列使用列类型并将所有数字包含在宏中，而是直接使用列类型。或者，考虑使用环境（将宽度设置为）而不是环境；这样就不必对表的内容使用。\MyAlignStabular*\textwidthtabular\small
\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx} % for 'S' column type
\usepackage[dvipsnames]{xcolor}
\newcommand\NavyBlue{\color{NavyBlue}} % 2 handy shortcut macros
\newcommand\Maroon{\color{Maroon}}
\begin{document}
\begin{table}[b]
\setlength{\tabcolsep}{0pt}
\caption{Results. The best and second-best result for each model
is marked in \textcolor{Maroon}{red} and \textcolor{NavyBlue}{blue}.\strut}

答案2
您在两个有问题的数字 ( \MyAlign{{\color{Maroon}8.89}}) 周围使用了双重括号。删除双重括号即可解决您的问题。
