将一批列相对于其上方较大的多列单元格居中

Question

在上面的表格中，多列下方的三列较小，并向左对齐。但是，我希望它们相对于上方最大的多列垂直居中，如下所示

\documentclass{book}

    \usepackage[x11names]{xcolor}

    \usepackage[a4paper]{geometry}

        \geometry{twoside=true, showframe=false}

        % Horizontal
        \geometry{inner=5mm, outer=5mm, includemp=true, bindingoffset=5mm, marginparsep=3.5mm, marginparwidth=15mm}

        % Vertical
        \geometry{top=20mm, vmarginratio=3:5, includehead=true, includefoot=true, headheight=8pt, headsep=14pt, footskip=5mm}

    \usepackage{ragged2e}


    \usepackage{tabularx}

        \newcolumntype{C}{ >{\arraybackslash \Centering}X }

    \usepackage{booktabs}
    \usepackage{makecell}

    \usepackage{mathtools}



\begin{document}

\begin{table*}[htb]

    % Center the table
    \centering

    \begin{tabularx}{\textwidth}{*{3}{l} >{\hsize=0.75\hsize}C !{\vrule width 0.25mm}*{3}{l} >{\hsize=0.75\hsize}C !{\vrule width 0.25mm}>{\hsize=1.5\hsize}C}

        \toprule

        \multicolumn{3}{c}{Exhaustive Search Method} & & \multicolumn{3}{c}{Proposed Method} & &

        \\
        \Xhline{0.25mm}

        33 & 36 & 35 & 4.90 & 33 & 36 & 35 & 4.90 & 36

        \Xhline{0.25mm}

        \multicolumn{3}{c}{\color{DodgerBlue2} \bfseries Time 8.8 s} & & \multicolumn{3}{c}{\color{DodgerBlue2} \bfseries Time 0.46 s} & &
        \\

        \bottomrule


    \end{tabularx}

\end{table*}

Answer 1

你对这个表很幸运：将长标题设置为零宽度可以解决问题。

我会完全避免使用垂直规则并用siunitx它来更好地对齐图形。

\documentclass{book}

\usepackage[a4paper]{geometry}
\usepackage[x11names]{xcolor}
\usepackage{ragged2e}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{makecell}
\usepackage{mathtools}
\usepackage{siunitx}

\geometry{
  % General
  twoside=true,
  showframe=false,
  % Horizontal
  inner=5mm,
  outer=5mm,
  includemp=true,
  bindingoffset=5mm,
  marginparsep=3.5mm,
  marginparwidth=15mm,
  % Vertical
  top=20mm,
  vmarginratio=3:5,
  includehead=true,
  includefoot=true,
  headheight=8pt,
  headsep=14pt,
  footskip=5mm,
}

\begin{document}

\begin{table}[htb]

像这样吗？

\documentclass{book}
\usepackage[x11names]{xcolor}
\usepackage[a4paper,twoside]{geometry}
\geometry{inner=5mm, outer=5mm, includemp=true,

          headheight=8pt, headsep=14pt, footskip=5mm}

\usepackage{ragged2e,tabularx}
\newcolumntype{C}{ >{\arraybackslash\Centering}X }

Answer 3

由于罪魁祸首是multicolumn标题的长度，我只需缩写这些标题并在标题文本中提及完整描述。因此，可以使用标准对齐的简单表格r，c。

\documentclass{book}
\usepackage[x11names]{xcolor}
\usepackage[a4paper]{geometry}
\geometry{twoside=true, showframe=false}

% Horizontal
\geometry{inner=5mm, outer=5mm, includemp=true, bindingoffset=5mm, marginparsep=3.5mm, marginparwidth=15mm}

% Vertical
\geometry{top=20mm, vmarginratio=3:5, includehead=true, includefoot=true, headheight=8pt, headsep=14pt, footskip=5mm}
\usepackage{ragged2e}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{makecell}
\usepackage{mathtools}

\begin{document}

\begin{table*}[htb]
    % Center the table
    \centering
    \begin{tabular}{*3{r}c*3{r}cc}
        \toprule
        \multicolumn{4}{c}{Exhaustive Search Method} & \multicolumn{4}{c}{Proposed Method} & \\
        \cmidrule(r){1-4}\cmidrule(lr){5-8}
        \multicolumn{3}{c}{Comb.\ POIs} & $\mathit{SDSCR_{\min}}$ & \multicolumn{3}{c}{Comb.\ POIs} & $\mathit{SDSCR_{\min}}$ & Ref.\ POIs        \\  \midrule
