来自 siunitx 的带有 S 列的溢出水平框

Question

根据先前问题我创建了下面给出的 MWE。我不明白的是，我收到了三个Overfull \hbox (9.9778pt to wide)警告。它们从何而来，因为它们没有出现在最后的超额/不足警告中，如何更改才能消除它们？

梅威瑟：

\documentclass{memoir}
\usepackage{siunitx}
\usepackage{calc}


\begin{document}
\begin{table}[tbp]
    \def\pm{\kern2.2pt\mathchar"2206}
    \newlength{\tabcolseptemp}
  \setlength{\tabcolseptemp}{\widthof{$\pm$}}
    \addtolength{\tabcolseptemp}{10pt}
    \centering
    \sisetup{
        table-figures-integer = 1,
        table-figures-decimal = 1,
        table-number-alignment = center,
        output-decimal-marker = {,},
        input-signs=,input-symbols=\pm
    }
            \begin{tabular}{S[table-figures-integer = 1,table-figures-decimal = 1] @{\hskip \tabcolseptemp} S[table-figures-integer = 2,table-figures-decimal = 1] @{\hskip \tabcolseptemp} S[table-figures-integer = 2,table-figures-decimal = 1]}
            \toprule
                     \multicolumn{1}{c}{\boldmath{$A$}}
                    & \multicolumn{1}{c}{\boldmath{$B$}}
                    & \multicolumn{1}{c}{\boldmath{$C$}}        \\
                \midrule
                1.5 \pm  & 12.0 \pm  & 15.0 \pm          \\  1.0 & 2.0 & 3.0         \\
                \bottomrule
            \end{tabular}
\end{table}
\end{document}

Answer 1

有一个更简单的方法：

\documentclass{memoir}
\usepackage{siunitx}

\newcommand{\tpm}{\ensuremath{\,\pm}}

\begin{document}
\begin{table}[tbp]

\centering

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

\begin{tabular}{
  S[table-format=1.1,table-space-text-post=\tpm]
  S[table-format=2.1,table-space-text-post=\tpm]
  S[table-format=2.1,table-space-text-post=\tpm]
}
\toprule
\multicolumn{1}{c}{\boldmath{$A$}} &
  \multicolumn{1}{c}{\boldmath{$B$}} &
  \multicolumn{1}{c}{\boldmath{$C$}} \\
\midrule
1.5 \tpm & 12.0 \tpm & 15.0 \tpm \\
1.0      &  2.0      &  3.0 \\
\bottomrule
\end{tabular}

\end{table}

\end{document}
