数字和 * 之间的额外空格

Question

我正在尝试构建一个包含数字和 ** 的表格，以便传递到某个重要性级别。出于某种原因，其中一列会在数字和 ** 之间添加额外的空格，我不明白为什么，有什么想法吗？顺便说一句，我使用 siunitx 按小数点居中。

\begin{center}
    \begin{table}[h]
        \begin{threeparttable}
            \begin{tabular}{c c S S c}
                
                \hline
                \textbf{Index} & \textbf{Data} & \textbf{ADF} & \textbf{KPSS} & \multicolumn{1}{c}{\textbf{Results}} \\
                
                \hline
                \multirow{2}{*}{\textbf{S\&P500}} & Prices & -0,52 & 6,59** & Non-stationary \\
                & Returns & -65,90** & 0,10 & Stationary \\
                
                \hline
                \multirow{2}{*}{\textbf{DAX}} & Prices  & -2,35 & 5,37** & Non-stationary \\
                & Returns & -62,77** & 0,05   & Stationary \\
                
                \hline
                \multirow{2}{*}{\textbf{FTSE}} & Prices & -2,72 & 4,04** & Non-stationary \\
                & Returns & -39,09** & 0,05 & Stationary \\
                
                \hline
                \multirow{2}{*}{\textbf{HSI}} & Prices & -3,88 & 0,98** & Non-stationary \\

            %\item \noindent Notes:
            %\item - The 5\% and 1\% critical value for the ADF test are $-3.41$ and $-3.96$, respectively.
            %\item - The 5\% and 1\% critical value for the KPSS test are 0.15 and 0.22, respectively.
            %\item - * and ** denote the rejection of the null hypothesis at 5\% and 1\% significance levels, %respectively.
            %\end{tablenotes}
        \end{threeparttable}
        \caption{\label{tab:3}Output of the ADF and KPSS tests, for the returns and prices of the four indices in study}
    \end{table}
\end{center}

您需要指定一个“模型”，它定义了为列类型中的数字保留的空间S[table-format=...]。此列类型不仅可以在默认的中使用tabular，还可以在许多派生的表格环境中使用，包括threeparttableOP示例中的。

以下示例c c S[table-format=-2.2{**}] S[table-format=2.2{**}] c使用了表格序言。根据所使用的文档类别和样式设置，输出可能会有所不同，但表格序言是可重复使用的。

\documentclass{article}
\usepackage{multirow}
\usepackage{siunitx}
\usepackage{threeparttable}

\begin{document}
\begin{table}[h]
    \centering
    \begin{threeparttable}
        \begin{tabular}{c c S[table-format=-2.2{**}] S[table-format=2.2{**}] c}
            
            \hline
            \textbf{Index} & \textbf{Data} & \textbf{ADF} & \textbf{KPSS} & \multicolumn{1}{c}{\textbf{Results}} \\
            
            \hline
            \multirow{2}{*}{\textbf{S\&P500}} & Prices & -0,52 & 6,59** & Non-stationary \\
