一、表格

\begin{table*}[htbp]
\caption{A general overview of video object tracking methods.} \label{table_1}
    \centering
    \setlength{\tabcolsep}{3mm}{
    \begin{tabular}{c|c|cccccc}
        \hline
        & Category&    Method   &    Publication &     
         BaseLine &    Platform &    FPS         &   GPUs \\
        \hline
        \multirow{5}{*}{\rotatebox{90}{Tracking}}&    & MDNet

\end{table*}

 二、并排插入图片

1、两张图片并排

\begin{figure}
\begin{center}
\begin{minipage}{0.45\linewidth}
\includegraphics[scale=0.1]{1.pdf}
\caption{example 1.}
\label{figure4}
\end{minipage}
\begin{minipage}{0.45\linewidth}
\includegraphics[scale=0.1]{1.pdf}
\caption{example 2.}
\label{figure5}
\end{minipage}
\end{center}
\end{figure}

 2、四张子图并排

\begin{figure}[tbp]
	\centering
	\subfigure[example a]%
      {
      \includegraphics[width=0.45\linewidth]{amss.pdf}
      \label{figure1a}
      }
	\subfigure[example b]%
      {
      \includegraphics[width=0.45\linewidth]{amss.pdf}
      \label{figure1b}
      }
	  \\
	\subfigure[example c]
      {
		\includegraphics[width=0.45\linewidth]{amss.pdf}
        \label{figure1c}
      }
	%\quad
	\subfigure[example d]
      {
		\includegraphics[width=0.45\linewidth]{amss.pdf}
        \label{figure1d}
      }
	\caption{figure1.}
\label{figure1}
\end{figure}
