当使用“m{width}”指定列宽时，如何强制水平居中？

以下是代码：

\documentclass{report}

\usepackage{amsmath}
\usepackage{amssymb, amsfonts}
\usepackage[flushleft]{threeparttable}
\usepackage{makecell}


\usepackage{ragged2e} 
\usepackage{tabularx}
\newcolumntype{L}{ >{ \arraybackslash \RaggedRight } X } % left justified
\newcolumntype{C}{ >{ \arraybackslash \Centering } X } % centered
\newcolumntype{R}{ >{ \arraybackslash \RaggedLeft } X } % right justified
\newcolumntype{J}{ >{ \arraybackslash \justifying } X } % justified
\renewcommand \tabularxcolumn [1] { >{ \centering } m{#1} }
\usepackage{booktabs}



\begin{document}


\begin{table*}[]



    % Table options
    \caption{Elasticity Values}
    \label{table:PV_mod_STC_comp2}

    % Center the table
    \centering

    % Stretch the table (vertically)
    \renewcommand{\arraystretch}{1.3}

    % t: puts the table in two columns format


    \begin{threeparttable}


        \begin{tabularx}{1\textwidth}{m{2.5cm}|C|C|m{1.2cm}|m{1.2cm}}



            \toprule


            \textbf{Customer type} & 
            \multicolumn{2}{c|}{\textbf{Set 1}}
            &
            \multicolumn{2}{c}{\textbf{Set 2}}
            \\
            \Xhline{0.2 mm}


            \textbf{Residential} &
            $-0.09$ to $-0.5$ &
            $-0.12$ to $-1.56$ & \Centering $1$ & \Centering $2$
            \\
            \Xhline{0.2 mm}


            \textbf{Commercial} & $-0.019$ to $-0.25$ & $-0.44$ to $-0.97$ & \Centering $3$ & \Centering $4$
            \\
            \Xhline{0.2 mm}


            \textbf{Industrial} & $-0.005$ to $-0.14$ & $-0.34$ to $-5.48$ & \Centering $5$ & 
            \Centering $6$
            \\



            \bottomrule



        \end{tabularx}



        % Table notes
        \begin{tablenotes}

            \item[a] This is a table note

        \end{tablenotes}

    \end{threeparttable}

\end{table*}

\end{document}

\Centering这是一个很好的结果，但是反复使用该命令是多余的。有没有办法强制所有单元格自动居中？

答案1

只需使用>{\centering\arraybackslash}m{some width}}。

我借此机会稍微改进了您的表格，将其放置\caption在threeparttable环境中并扩大第一列以使所有单元格都位于一行中。我还提出了一种更好看的布局（在我看来），没有垂直线，水平线更少，用垂直填充代替。

答案2

  • 在序言中删除\renewcommand \tabularxcolumn [1] { >{ \centering } m{#1} }。这是错误的。也许你喜欢这样

    \newcolumntype{M}[1]{>{\Centering} m{#1} }

  • 在列类型定义\begin{tabularx}{1\textwidth}{m{2.5cm}|C|C|m{1.2cm}|m{1.2cm}}中用替换\begin{tabularx}{1\textwidth}{m{2.5cm}|C|C|*{2}{>{\centering\arraybackslash}m{1.2cm}|}}。

题外话： - 在threeparttable通常其中-在列类型定义中\caption{...}使用\Raggedleft，，没有必要使用。\RaggedRightCentering\arraybackslash
