如何为表格内的各个表格添加标题？

我有以下代码，可并排创建三个表格。如何为每个表格分别添加不同的标题？

\begin{table}
    \footnotesize
    \begin{tabular}{|l|l|}  
        \hline
        Service  & Features \\
        \hline
        $S_{11}$ & $F_1$    \\
        $S_{12}$ & $F_1$    \\
        $S_{13}$ & $F_1$    \\
        $S_{14}$ & $F_1$    \\
        $S_{15}$ & $F_2$    \\
        \hline
    \end{tabular}
    \hfill
    \begin{tabular}{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{21}$ & $F_3$    \\
        $S_{22}$ & $F_3$    \\
        $S_{23}$ & $F_3$    \\
        $S_{24}$ & $F_3$    \\
        $S_{25}$ & $F_4$    \\
        \hline
    \end{tabular}
    \hfill
    \begin{tabular}{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{31}$ & $F_5$    \\
        $S_{32}$ & $F_5$    \\
        $S_{33}$ & $F_5$    \\
        \hline
    \end{tabular}

    \caption{99 most frequent hashtags in the data set.}
\end{table}

我不太清楚您喜欢如何在表格中添加标题，因此下面是两个可能的示例：

在此处输入图片描述

第一个用于tabularx在行中展开表格，第二个用于使用subtable来自包的环境subcaption：

\documentclass{article}
\usepackage{tabularx}
\usepackage{subcaption}

\begin{document}
    \begin{table}[htb]
\begin{tabularx}{\linewidth}{*{3}{>{\centering\arraybackslash}X}}
    \begin{tabular}[b]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{11}$ & $F_1$    \\
        $S_{12}$ & $F_1$    \\
        $S_{13}$ & $F_1$    \\
        $S_{14}$ & $F_1$    \\
        $S_{15}$ & $F_2$    \\
        \hline
    \end{tabular}
\caption{The first table}
    &
    \begin{tabular}[b]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{21}$ & $F_3$    \\
        $S_{22}$ & $F_3$    \\
        $S_{23}$ & $F_3$    \\
        $S_{24}$ & $F_3$    \\
        $S_{25}$ & $F_4$    \\
        \hline
    \end{tabular}
\caption{The second table}
    &
    \begin{tabular}[b]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{31}$ & $F_5$    \\
        $S_{32}$ & $F_5$    \\
        $S_{33}$ & $F_5$    \\
        \hline
    \end{tabular}
\caption{The third table}
    \end{tabularx}
    \end{table}
or
    \begin{table}[htb]
\begin{subtable}[b]{0.3\linewidth}
    \begin{tabular}{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{11}$ & $F_1$    \\
        $S_{12}$ & $F_1$    \\
        $S_{13}$ & $F_1$    \\
        $S_{14}$ & $F_1$    \\
        $S_{15}$ & $F_2$    \\
        \hline
    \end{tabular}
\caption{The first table}
    \end{subtable}
    \hfill
\begin{subtable}[b]{0.3\linewidth}
    \begin{tabular}[b]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{21}$ & $F_3$    \\
        $S_{22}$ & $F_3$    \\
        $S_{23}$ & $F_3$    \\
        $S_{24}$ & $F_3$    \\
        $S_{25}$ & $F_4$    \\
        \hline
    \end{tabular}
\caption{The second table}
    \end{subtable}
    \hfill
\begin{subtable}[b]{0.3\linewidth}
    \begin{tabular}[b]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{31}$ & $F_5$    \\
        $S_{32}$ & $F_5$    \\
        $S_{33}$ & $F_5$    \\
        \hline
    \end{tabular}
\caption{The third table}
    \end{subtable}
\caption{99 most frequent hashtags in the data set.}
    \end{table}
\end{document}

借助 minipages 和软件包的帮助capt-of：

\documentclass{article}
\usepackage{geometry}
\usepackage{capt-of}
\begin{document}
\noindent
\begin{minipage}[t]{0.25\textwidth}
    \footnotesize
    \begin{tabular}[t]{|l|l|}  
        \hline
        Service  & Features \\
        \hline
        $S_{11}$ & $F_1$    \\
        $S_{12}$ & $F_1$    \\
        $S_{13}$ & $F_1$    \\
        $S_{14}$ & $F_1$    \\
        $S_{15}$ & $F_2$    \\
        \hline
    \end{tabular}
\end{minipage}\hfill
\begin{minipage}[t]{0.25\textwidth}
    \begin{tabular}[t]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{21}$ & $F_3$    \\
        $S_{22}$ & $F_3$    \\
        $S_{23}$ & $F_3$    \\
        $S_{24}$ & $F_3$    \\
        $S_{25}$ & $F_4$    \\
        \hline
    \end{tabular}
\end{minipage}\hfill
\begin{minipage}[t]{0.25\textwidth}
    \begin{tabular}[t]{|l|l|}
        \hline
        Service  & Features \\
        \hline
        $S_{31}$ & $F_5$    \\
        $S_{32}$ & $F_5$    \\
        $S_{33}$ & $F_5$    \\
        \hline
    \end{tabular}
\end{minipage}
\begin{minipage}[t]{0.25\textwidth}
        \captionof{table}{Caption of first table}
\end{minipage}\hfill
\begin{minipage}[t]{0.25\textwidth}
         \captionof{table}{Caption of second table}
\end{minipage}\hfill
\begin{minipage}[t]{0.25\textwidth}
         \captionof{table}{Caption of third table}
\end{minipage}
