Latex插入图片

1. 一张图片占两行

\begin{figure*}[htbp] %这个星号就是让你的图占满一行

\includegraphics[width=.95\linewidth]{SADgym-gazebo.png}
\caption{the SAD gym-gazebo architecture where left block represents the robot simulation environment, which including Autopilot, ROS, Gazebo, Gym and Server-Interface. right block represents the specific algorithm implementation. Which including algorithms, other functions and client-Interface.}
\label{fig}
\end{figure*}

2. 并排插入两张图片

\begin{figure}[htbp]
\subfigure[PPO]{
\begin{minipage}[t]{0.45\linewidth}
\centering
\includegraphics[height=4cm,width=4.2cm]{R-ppo.pdf}
\end{minipage}%

\end{minipage}
}
\caption{Comparison of single-UAV average Reward with A3C(a),AC(b) DDPG(c), DDQN(d) PPO(e) and MADDPG(f)}
\end{figure}

3. 并排插入多张图片(占两行)

\end{figure*}

4.插入表格

\begin{table}[htbp]
\centering
\caption{Different algorithm code change ratio}
\begin{tabular}{ccccccc}%l=left, r=right,c=center分别代表左对齐，右对齐和居中，字母的个数代表列数
\hline
