表格和 SI \unit 命令 \uA 给出了一个奇怪的 t

Question

我刚刚偶然发现了这个使用 的奇怪问题siunitx。我正在做报告（IEEE 风格中是强制性的），似乎 micro 前缀在环境中给了我这个奇怪的 t tabular。我在序言中指定了我希望\per选项是什么样子，作为分割线。

在 W10 上通过 texstudio 和 XeLaTeX

\begin{table}[h]
    \renewcommand{\arraystretch}{1.3}
    \caption{the caption}
    \label{tab:ref-of-my-table}
    \centering
    \begin{tabular}{ll*{1}{S}l}
        \toprule
        {A} &   {B} & {Value} & {Unit}\\
        \midrule
        AA  &   & 0.46  & \unit{\volt} \\
        BB  &   & 0.6 & \unit{\volt} \\
        EE  &   & 115 & \unit{\uA \per  \volt \squared} \\
        GG  &   & 40  & \unit{\micro \ampere \per  \volt \squared} \\
        Slew rate   &   &   & \\
        Voltage swing IN    &   &   &    \\
        Voltage swing OUT   &   &   &    \\
        \bottomrule
    \end{tabular}
\end{table}

Answer 1

使用 XeLaTeX，你应该不是使用fontenc和textcomp。

如果要符合 IEEEtran 的标准 Times 字体，可以加载newtx。

也是subcaption​不是兼容IEEEtran，因此您不应加载它。该subfloat包不会以与相同的方式执行“子浮点数” subcaption。如果您确实需要子浮点数，请执行

\usepackage[caption=false]{subfig}

caption加载（或）的结果subcaption是标题将不符合样式IEEEtran。

更正内容如下：
