使用表格將表格內容置中對齊

Question

我希望將第二列和第三列等長並放在中間。

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[!ht]
    %\begin{tabularx}{\textwidth}{@{}Y*{3}{W}@{}}
\centering
 \begin{tabular}{ccc}
    \toprule
    & \multicolumn{2}{c}{\textbf{Testing Testing Testin}} \\
    & \multicolumn{2}{c}{\textbf{Making into Secondline (\%)}} \\
     \cmidrule{2-3}
    & \small {\textbf{AA}}
     & \small {\textbf{BB}} \\
     \midrule
    Test 1 & 33 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
        \bottomrule
    \end{tabular}

\end{table}

\end{document}

結果：

我希望將第二列和第三列等長並放在中間。

這是一種幫助的方法parbox

\documentclass{article}
\usepackage{booktabs}

\begin{document}

\begin{table}[!ht]
    %\begin{tabularx}{\textwidth}{@{}Y*{3}{W}@{}}
\centering
 \begin{tabular}{ccc}
    \toprule
    & \multicolumn{2}{c}{\textbf{Testing Testing Testin}} \\
    & \multicolumn{2}{c}{\textbf{Making into Secondline (\%)}} \\
     \cmidrule{2-3}
    &  {\parbox{3cm}{\small\hfil\textbf{AA}\hfill}}
     & {\parbox{3cm}{\small\hfil\textbf{BB}\hfill}} \\
     \midrule
    Test 1 & 33 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
        \bottomrule
    \end{tabular}

\end{table}

\end{document}

Answer 2

這是一個可能的解決方案，基於siunitx數字的良好對齊（居中右對齊）。列中的非數字S必須用一對大括號括起來並自動居中。此外，S柱的寬度可以選擇。該解決方案還依賴於makecell，它允許在標準單元格中換行，以及\makecell和\thead命令參數的通用格式。

\documentclass{article}
\usepackage{array}
\usepackage{booktabs, makecell}
\renewcommand{\theadfont}{\small\bfseries}
\usepackage{siunitx}

\begin{document}

\begin{table}[!ht]
\centering
\sisetup{table-format=3.0, table-number-alignment=center, table-column-width=1.5cm}
 \begin{tabular}{cSS}
    \toprule
    & \multicolumn{2}{c}{\small\bfseries Testing Testing Testin} \\
    & \multicolumn{2}{c}{\thead{\makebox[0pt]{Making into Secondline}\\ (\%)}} \\
     \cmidrule{2-3}
    &{\small \textbf{AA}}
     & {\small\textbf{BB}} \\
     \midrule
    Test 1 & 33 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
    Test 2 & 57 & 73 \\
        \bottomrule
    \end{tabular}
\end{table}

\end{document}

這使得列“Z”以最長標題行的一半寬度精確居中。您只需對 LateX 說每個表格之前的標題行的寬度是多少\settowidth： width ：

\documentclass{article}
\usepackage{booktabs,array}
\newlength{\xxx} % suggestion:  change "xxx" for something meaningful 
\newcolumntype{Z}{>{\hfil}p{.5\xxx}}
\begin{document}

\settowidth{\xxx}{\textbf{Making into Secondline (\%)}}

\begin{tabular}{cZZ} \toprule
& \multicolumn{2}{c}{\textbf{Testing Testing Testin}} \\
& \multicolumn{2}{c}{\textbf{Making into Secondline (\%)}} \\\cmidrule{2-3}
& \small {\textbf{AA}}  & \small {\textbf{BB}} \\\midrule
Test 1 & 33 & 73 \\
Test 2 & 57 & 73 \\
Test 2 & 57 & 73 \\
Test 2 & 57 & 73 \\
Test 2 & 57 & 73 \\
Test 2 & 57 & 73 \\
Test 2 & 57 & 73 \\\bottomrule
\end{tabular}

\end{document}
