答案1

我将重新整理材料的几个方面tabularx。它们如下（无特定顺序）：

  • 通过省略所有垂直线并使用更少但间距适当的水平线，使表格呈现出更加开放和吸引人的“外观”。

  • 将材料置于 6 个数据列的中心

  • 允许在第一列中使用连字符，即使在每个单元格的第一个单词中也是如此

  • 将单元格内容居中垂直通过适当的重新定义\tabularxcolumn

  • 放下加粗——除非你想让人觉得你喜欢喊您的读者...——而是使用合理放置的\cmidrule指令在表格的标题部分提供更多的视觉结构。

我建议使用以下变体，类似于Mico 的回答，其中我将重复的日期放在表格下方的多列中。根据单元格的实际内容，这可以帮助节省一些空间，并可以避免第一列的换行。

\documentclass[a4paper, 11pt]{article}
\usepackage[left=3cm,top=3cm,right=3cm]{geometry}

\usepackage{caption} 
\usepackage{tabularx} 
\usepackage{booktabs}

\begin{document}
\begin{table}[ht]
\caption{Computed Descriptors}
\label{key}
    \begin{tabularx}{\textwidth}{Xcccccc}
        \toprule
        Key figures 
          & \multicolumn{2}{c}{Toluene} 
            & \multicolumn{2}{c}{Nicotinamide} 
              & \multicolumn{2}{c}{Adenine}\\
        \cmidrule(r){2-3} \cmidrule(lr){4-5} \cmidrule(l){6-7}
          & 1st run  & 2nd run  & 1st run  & 2nd run  & 1st run  & 2nd run  \\
        \midrule

        \bottomrule
        \multicolumn{7}{l}{\small 1st run: 28.09.2020, 2nd run: 01.10.2020}

像这样？

在此处输入图片描述

\documentclass[a4paper, 11pt]{article}
\usepackage[margin=3cm]{geometry}
\usepackage{pdfpages} % inclusion of external multi-page PDF documents
\usepackage{tabularx} % Tabulars with adjustable-width columns
\newcolumntype{Y}{>{\small\raggedright\arraybackslash}X}

\begin{document}

\begin{table}[ht]
    \begin{tabularx}{\textwidth}{|Y||Y|Y|Y|Y|Y|Y|}
        \hline
\textbf{Key figures} 
    &   \multicolumn{2}{c|}{\textbf{Toluene}}
            &   \multicolumn{2}{c|}{\textbf{Nicotinamide}}  
                    &   \multicolumn{2}{c|}{\textbf{Adenine}}\\
        \hline
        \hline
\textbf{Retention time} 
    & 1 & 2 & 3 & 4 & 5 & 6\\
        \hline
    \end{tabularx}

\end{document}

不过，我会按如下方式写您的表格（考虑到编辑问题中添加的信息）：

\documentclass[a4paper, 11pt]{article}
\usepackage[margin=3cm]{geometry}
\usepackage{booktabs, makecell, tabularx} 
\renewcommand\thead{\small\bfseries}
\newcolumntype{Y}{>{\raggedright\arraybackslash}X}
\newcommand\mcc[1]{\multicolumn{1}{c}{#1}}

\begin{document}

\begin{table}[ht]
\small
\renewcommand{\tabularxcolumn}[1]{m{#1}}
\setlength\tabcolsep{4pt}
    \begin{tabularx}{\textwidth}{@{} >{\small\bfseries\hsize=1.24\hsize}Y
                                               *{6}{>{\hsize=0.96\hsize}Y} @{}}
        \toprule
Key figures
    &   \multicolumn{2}{c}{\thead{Toluene}}
            &   \multicolumn{2}{c}{\thead{Nicotinamide}}
                    &   \multicolumn{2}{c}{\thead{Adenine}}                 \\
    \cmidrule(l){2-3}
    \cmidrule(l){4-5}
    \cmidrule(l){6-7}
Retention time
        & 1st run (28.09.2020) & 2nd run (01.10.2020) & 1st run (28.09.2020) & 2nd run (01.10.2020) & 1st run (28.09.2020) & 2nd run (01.10.2020) \\
 %    & \mcc{1}   & \mcc{2}   & \mcc{3}   & \mcc{4}   & \mcc{5}   & \mcc{6}   \\
    \midrule
