\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 $4$

        \end{tabularx}



        % Table notes
        \begin{tablenotes}

        \end{tablenotes}

    \end{threeparttable}

\end{table*}

\Centering這是一個很好的結果，但是一遍又一遍地使用該命令是多餘的。有沒有辦法強制所有儲存格自動居中？

答案1

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

我藉此機會稍微改進了您的表格，將其放置\caption在threeparttable環境中並放大第一列以使所有單元格位於一行上。我還提出了一個更好看的（在我看來）佈局，沒有垂直線，更少的水平規則，用垂直填充代替。

答案2

  • 在序言中刪除\renewcommand \tabularxcolumn [1] { >{ \centering } m{#1} }.這是錯誤的。也許你喜歡有類似的東西

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

  • 在列類型定義中替換\begin{tabularx}{1\textwidth}{m{2.5cm}|C|C|m{1.2cm}|m{1.2cm}}為\begin{tabularx}{1\textwidth}{m{2.5cm}|C|C|*{2}{>{\centering\arraybackslash}m{1.2cm}|}}。

題外話： - 通常在它的threeparttable內部\caption{...}- 在列類型定義中使用\Raggedleft, \RaggedRight，Centering沒有必要使用\arraybackslash。
