将表格垂直居中在子浮动内

以下 MWE 并排生成两个表格：

\documentclass{report}

\usepackage{siunitx}
\usepackage[version=3]{mhchem}

\newcommand{\ul}{\si{\micro\liter}}
\newcommand{\uM}{\si{\micro}M}
\newcommand{\degc}{\si{\celsius}}

\begin{document}

\begin{table}[h]

                \multicolumn{2}{c}{4\degc}      & $\infty$  \\
                \bottomrule
            \end{tabu}
        }
\end{table}

\end{document}

然而，第二张表的位置很尴尬：

我希望将第二张较小的表格向下移动，以便它位于较大的第一张表格的中心。

由于您没有为\subfloats 使用任何标题，因此您应该将其删除；表格默认是垂直居中的：

在此处输入图片描述

\documentclass{report}
\usepackage[margin=1in]{geometry}% Just for this example

\usepackage{tabu,booktabs,multirow,siunitx}
\usepackage[version=3]{mhchem}

\newcommand{\ul}{\si{\micro\liter}}
\newcommand{\uM}{\si{\micro}M}
\newcommand{\degc}{\si{\celsius}}

\begin{document}

  \caption{PCR conditions}

  \begin{tabu}{lrrrr}
    \toprule
                    & 1X        & 2X        & Total     & Per tube  \\

  \begin{tabu}{ccc}

    \bottomrule
  \end{tabu}
\end{table}

答案2

如果您确实想使用\subfloat，并且由于它会自动对齐顶部，您必须谎报禁忌的大小。另一方面，基线已经垂直居中。

\documentclass{report}

\usepackage{tabu}
\usepackage{booktabs}
\usepackage{multirow}
\usepackage{subfig}
\usepackage{siunitx}
\usepackage[version=3]{mhchem}

\newcommand{\ul}{\si{\micro\liter}}
\newcommand{\uM}{\si{\micro}M}
\newcommand{\degc}{\si{\celsius}}

% used to compute height of larger tabu
\newsavebox{\boxA}
\newlength{\lenA}

% not really needed after all
\newsavebox{\boxB}
\newlength{\lenB}

\begin{document}

\savebox{\boxA}{
  \begin{tabu}{lrrrr}
     \toprule
                     & 1X        & 2X        & Total     & Per tube  \\
     \midrule
     \ce{H2O}        & 9.10 \ul  & 18.20 \ul & 18.20 \ul & 9.10 \ul  \\
     2X KAPA HiFi    & 10.00 \ul & 20.00 \ul & 38.20 \ul & 19.10 \ul \\
     AMPG1 (10 \uM ) & 0.40 \ul  & 0.80 \ul  & 39.00 \ul & 19.50 \ul \\
     ORIG1 (10 \uM ) & 0.40 \ul  & 0.80 \ul  & 39.80 \ul & 19.90 \ul \\
     Template        & 0.25 \ul  & ---       & ---       & ---       \\
     \midrule
     \textbf{Total}  & 20.00 \ul & ---       & ---       & ---       \\
     \bottomrule
  \end{tabu}
}
\settoheight{\lenA}{\usebox{\boxA}}% distance from top to baseline

\savebox{\boxB}{
     \begin{tabu}{ccc}
        \toprule
        \multicolumn{2}{c}{95\degc}     & 3:00      \\
        \midrule
        \multirow{3}{*}{x35} & 98\degc  & 0:30      \\
                             & 54\degc  & 0:20      \\
                             & 72\degc  & 1:00      \\
        \midrule
        \multicolumn{2}{c}{72\degc}     & 3:00      \\
        \multicolumn{2}{c}{4\degc}      & $\infty$  \\
        \bottomrule
      \end{tabu}
}
\settoheight{\lenB}{\usebox{\boxB}}

\begin{table}[h]
        \centering
        \caption{PCR conditions}
        \subfloat{\usebox{\boxA}}
        \subfloat{\raisebox{0pt}[\lenA]{\usebox{\boxB}}}
\end{table}

\end{document}

注意：任何\raisebox参数组合都可以起作用，例如基线降低的距离和从顶部到基线的（假）距离之和\lenA。

这是一个解决方案，其中单位移到数字之上，并\uM定义了新的宏。我认为这既澄清了代码，也澄清了符号。
