我如何收紧这些表列？

我如何收紧这些表列？

我希望 A1、A3 和 B1 列更像 B3 列，其组外侧面没有任何单元格填充。

Table with less than tight columns

我能做到吗？我现在的代码如下：

\documentclass{article}
\usepackage{booktabs}
\begin{document}
  \begin{table*}\centering
    \begin{tabular}{@{}lccccccc@{}}\toprule
      & \multicolumn{3}{c}{A} & \phantom{abc}& \multicolumn{3}{c}{B}\\ \cmidrule{2-4} \cmidrule{6-8}
      & 1 & 2 & 3 && 1 & 2 & 3\\
      \midrule
      C     &       0.60  &       0.951 &       0.245         & &       1.151         &       1.563         &       0.586         \\
                  &     (0.262)         &     (0.364)         &     (0.310)         & &     (0.620)         &     (0.905)         &     (0.696)         \\
      \midrule
      \(N\)       &      919629         &      468093         &      451536         & &      186271         &       94771         &       91500         \\

      \bottomrule
    \end{tabular}
  \end{table*}
\end{document}

答案1

除了删除空列之外，我还会使用软件包的工具将数字排列在小数点标记上dcolumn。

\documentclass{article}
\usepackage{booktabs,dcolumn}
\newcolumntype{d}[1]{D..{#1}}
\newcommand\mc[1]{\multicolumn{1}{c}{#1}} % handy shortcut macro
\begin{document}
\begin{table}
\centering
\begin{tabular}{@{} l *{6}{d{2.4}} @{}}
\toprule
& \multicolumn{3}{c}{A} & \multicolumn{3}{c@{}}{B}\\ \cmidrule(lr){2-4} \cmidrule(l){5-7}
& \mc{1} & \mc{2} & \mc{3} & \mc{1} & \mc{2} & \mc{3} \\
\midrule
C & 0.60    & 0.951   & 0.245   & 1.151   & 1.563   & 0.586   \\
  & (0.262) & (0.364) & (0.310) & (0.620) & (0.905) & (0.696) \\
\midrule
$N$ & \mc{919629} & \mc{468093} & \mc{451536} & \mc{186271} &  \mc{94771} &  \mc{91500} \\
\bottomrule
\end{tabular}
\end{table}
\end{document}

答案2

我会写出稍微不同一点的表格：

enter image description here

\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx}% added

\begin{document}
  \begin{table*}\centering
\begin{tabular}{ l *{6}{S[input-symbols = ( ),
                          table-space-text-pre={(},
                          table-space-text-post={)},
                          table-format=1.3]} }% changed
    \toprule
        & \multicolumn{3}{c}{A}                         & \multicolumn{3}{c}{B}                         \\
    \cmidrule(lr){2-4}
    \cmidrule(lr){5-7}
        & {1}           & {2}           & {3}           & {1}           & {2}           & {3}           \\
    \midrule
C       &  0.60         &  0.951        &  0.245        &  1.151        &  1.563        &  0.586        \\
        & (0.262)       & (0.364)       & (0.310)       & (0.620)       & (0.905)       & (0.696)       \\
  \midrule
\(N\)   & \num{919629}  & \num{468093}  & \num{451536}  & \num{186271}  & \num{94771}   & \num{91500}   \\ %changed
    \bottomrule
\end{tabular}
  \end{table*}
\end{document}

或者最终：

enter image description here

\documentclass{article}
\usepackage{booktabs}
\usepackage{siunitx}

\begin{document}
  \begin{table*}\centering
\begin{tabular}{ l *{3}{S[input-symbols = ( ),
                          table-space-text-pre={(},
                          table-space-text-post={)},
                          table-format=1.3]}
                    c
                   *{3}{S[input-symbols = ( ),
                          table-space-text-pre={(},
                          table-space-text-post={)},
                          table-format=1.3]} }
    \toprule
        & \multicolumn{3}{c}{A}                         && \multicolumn{3}{c}{B}                        \\
    \cmidrule(lr){2-4}
    \cmidrule(lr){6-8}
        & {1}           & {2}           & {3}           && {1}          & {2}           & {3}           \\
    \midrule
C       &  0.60         &  0.951        &  0.245        &&  1.151       &  1.563        &  0.586        \\
        & (0.262)       & (0.364)       & (0.310)       && (0.620)      & (0.905)       & (0.696)       \\
  \midrule
\(N\)   & \num{919629}  & \num{468093}  & \num{451536}  && \num{186271} & \num{94771}   & \num{91500}   \\
    \bottomrule
\end{tabular}
  \end{table*}
\end{document}

（不同之处在于插入的空列会在表格 A 部分和 B 部分之间增加更多空间。）

答案3

(lr)与 s 结合使用\cmidrule并删除\phantom{abc}，它会增加太多空间。

\documentclass{article}
\usepackage{booktabs}
\begin{document}
  \begin{table*}\centering
    \begin{tabular}{@{}lccccccc@{}}
        \toprule
                                             &    \multicolumn{3}{c}{A}    &  &    \multicolumn{3}{c@{}}{B}    \\
        \cmidrule(lr){2-4} \cmidrule(l){6-8} &    1    &    2    &    3    &  &    1    &    2    &    3    \\ \midrule
        C                                    &  0.60   &  0.951  &  0.245  &  &  1.151  &  1.563  &  0.586  \\
                                             & (0.262) & (0.364) & (0.310) &  & (0.620) & (0.905) & (0.696) \\ \midrule
        \(N\)                                & 919629  & 468093  & 451536  &  & 186271  &  94771  &  91500  \\ \bottomrule
    \end{tabular}
  \end{table*}
\end{document}

答案4

这是通过改变

\begin{tabular}{@{}lccccccc@{}}

到

\begin{tabular}{@{}l@{}ccc@{}c@{}ccc@{}}
