使表格水平填充整个页面

Question

我正在尝试将表格填满整个页面（水平）。我有下表：

\begin{table}\caption{Descriptive statistics of variables}\label{Statistics of all countries}
 \toprule
\small
\begin{tabularx}{\textwidth}{@{}LllllllllL@{}}
 & \multicolumn{4}{c}{Interest rate (basis points)} & \multicolumn{4}{c}{Debt-to-GDP (\%)} & \\
    Countries & $\mu$ & Max &  Min & $\sigma$ & $\mu$ & Max & Min & $\sigma$ \\
    \cmidrule(r){1-1}
      \cmidrule(lr){2-5}
\cmidrule(lr){6-9}
    Austria & 300.19 & 544.98 & -78.17 & 174.18 & 73.34 & 85.90 & 65.00 & 6.25  \\
    Belgium &  299.77 & 573.61 & -41.65 & 176.12 & 102.99 & 117.40 & 87.3 & 7.40 \\
    Finland &  258.71 & 533.34 & -241.38 & 186.23 & 44.19 & 64.20 & 28.70 & 10.54\\

    \cmidrule(r){1-1}
      \cmidrule(lr){2-5}
        \cmidrule(lr){6-9}
 Full sample & 720.47 & 3816.33 & 38.62 & 833.42 & 1.66 & 21.45 & 0.00 & 2.83
 \\
\end{tabularx}
\bottomrule
\addlinespace
\captionsetup{width=\textwidth}
\caption*{\textit{Descriptive statistics of all countries over the years 2000 until 2020 Q2 , excluding the crisis. The mean, maximum, minimum and standard deviation is given.}  }
\end{table}

我故意省略了多行。我尝试使用 \textwidth 填充页面，但没有效果。

Answer 1

不幸的是，并不完全清楚，你的表格应该是什么样的：

• 定义了 11 列，但只使用了 9 列
• 桌子线不能位于外部tabularx环境（或任何其他环境）
• 我将使用包S中定义的siunitx数字列，这些数字以小数点对齐

清理代码片段后，带有表格的可能 MWE (最小工作示例) 可以是：

\documentclass{article}
\usepackage[skip=1ex,
            font=small, 
            labelfont=bf]{caption}
\usepackage{booktabs, tabularx}
\newcolumntype{C}{>{\centering\arraybackslash}X}
\NewExpandableDocumentCommand\mcx{O{1}m}{\multicolumn{#1}{C}{#2}}
\usepackage{siunitx}

\begin{document}
    \begin{table}
\caption{Descriptive statistics of variables}
\label{Statistics of all countries}
    \setlength\tabcolsep{3pt}
\begin{tabularx}{\textwidth}{ l 
                     S[table-format= 3.2]
                     S[table-format= 4.2]
                     S[table-format=-3.2]
                *{3}{S[table-format= 3.2]} 
                *{2}{S[table-format= 2.2]}
                             }
    \toprule
    & \multicolumn{4}{c}{Interest rate (basis points)} 
        & \multicolumn{4}{c}{Debt-to-GDP (\%)}              \\
    \cmidrule(l){2-5}
    \cmidrule(l){6-9}
