子图子表

子图

子图的实现为使用 subcaption 所提供的 subfigure 环境：

\begin{figure}[!htbp]
    \centering
    \begin{subfigure}[b]{0.35\textwidth}
      \includegraphics[width=\textwidth]{oaspl_a}
      \caption{}
      \label{fig:oaspl_a}
    \end{subfigure}%
    ~% add desired spacing
    \begin{subfigure}[b]{0.35\textwidth}
      \includegraphics[width=\textwidth]{oaspl_b}
      \caption{}
      \label{fig:oaspl_b}
    \end{subfigure}
    \\% line break
    \begin{subfigure}[b]{0.35\textwidth}
      \includegraphics[width=\textwidth]{oaspl_c}
      \caption{}
      \label{fig:oaspl_c}
    \end{subfigure}%
    ~% add desired spacing
    \begin{subfigure}[b]{0.35\textwidth}
      \includegraphics[width=\textwidth]{oaspl_d}
      \caption{}
      \label{fig:oaspl_d}
    \end{subfigure}
    \bicaption{总声压级。(a) 这是子图说明信息，(b) 这是子图说明信息，(c) 这是子图说明信息，(d) 这是子图说明信息。}{OASPL.(a) This is the explanation of subfig, (b) This is the explanation of subfig, (c) This is the explanation of subfig, (d) This is the explanation of subfig.}
    \label{fig:oaspl}
\end{figure}

子表

子表的实现为使用 subcaption 所提供的 subtable 环境：

\begin{table}[!htbp]
    \bicaption{这是一个样表。}{This is a sample table.}
    \label{tab:sample_multitables}
    \centering
    \footnotesize% fontsize
    \setlength{\tabcolsep}{4pt}% column separation
    \renewcommand{\arraystretch}{1.2}%row space 
    \begin{subtable}[t]{0.45\textwidth}
        \centering
        \bicaption{子表1。}{Subtable 1.}
        \label{tab:sample_1}
        \begin{tabular}{lcccccccc}
            \hline
            Row number & \multicolumn{8}{c}{This is a multicolumn} \\
            %\cline{2-9}% partial hline from column i to column j
            \hline
