siunitx 表中数字的小数分隔符为逗号，而不是句号

    Diastasetal}
   {l *{5}{c}}
   {\dage{#1}, \diastase{#1}}
\end{table}

\end{document}

输出

为什么小数部分的数字用一个圆点而不是逗号作为小数分隔符？（我按照 egreg 在评论中的建议添加了

\sisetup{
  output-decimal-marker = {,}
}

但这确实有帮助。）

答案1

您需要使用siunitx表列的特征：

\begin{table}
  \printtable*
   {5}
   {Antal d{\o}gn \hspace*{0.5em},
    Diastasetal}
   {l *{5}{S[table-parse-only]}}
   {\dage{#1}, \diastase{#1}}
\end{table}

将打印
