Answer 1

Saya akan mengatur ulang beberapa aspek tabularxmateri. Mereka tidak dalam urutan tertentu:

• Berikan tabel "tampilan" yang lebih terbuka dan menarik dengan menghilangkan semua garis vertikal dan dengan menggunakan lebih sedikit garis horizontal, tetapi berjarak cukup.

• Pusatkan materi di 6 kolom data

• Izinkan tanda hubung di kolom pertama, bahkan di kata pertama setiap sel

• Pusatkan isi sel secara vertikal melalui definisi ulang yang sesuai dari\tabularxcolumn

• Drop huruf tebal - kecuali jika Anda ingin dianggap sebagai menyukai untuk berteriak di pembaca Anda ... - dan, sebaliknya, menyediakan struktur yang lebih visual di bagian header tabel dengan penggunaan bijaksana ditempatkan \cmidrulearahan.

Answer 2

Saya menyarankan varian berikut, mirip dengan jawaban Mico , di mana saya menempatkan tanggal berulang dalam multikolom di bawah tabel. Bergantung pada konten sel yang sebenarnya, ini dapat membantu menghemat ruang dan dapat menghindari penggalan baris di kolom pertama.

\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
        Retention time & 1&2&3&4&5&5\\
        Peak area  \\ 
        Theoretical plates (USP)  \\
        Assymetry \\
        Resolution \\
        \bottomrule
        \multicolumn{7}{l}{\small 1st run: 28.09.2020, 2nd run: 01.10.2020}
    \end{tabularx}

\end{table}

Answer 3

Seperti ini?

\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}
    \caption{Computed Descriptors}
\end{table}

Namun, saya akan menulis tabel Anda sebagai berikut (mempertimbangkan informasi tambahan dalam pertanyaan yang diedit):

\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}

    \midrule
