In your case, wrap the figures with \raisebox{} and lower the figures by us= ing negative units. Since I don't have the png, you may need to use the "tr= ials and errors" method to find the best layout you need. My attempt is displayed below. \begin{document} \begin{table}[!h] \centering \caption{=E4=BA=8C=E7=B6=AD=E8=BD=89=E6=8F=9B=E7=9A=84=E5=B9=BE=E4=BD=95=E6= =80=A7=E8=B3=AA} \label{Ch4_Geometric2} \begin{tabular}[t]{cccc}=20 \par\vspace{1cm} =E7=A8=AE=E9=A1=9E & =E8=87=AA=E7=94=B1=E5=BA=A6 & =E7=9F=A9=E9=99=A3 & =E5= =9E=8B=E6=85=8B=E8=AE=8A=E5=8C=96\\=20 \par\vspace{1cm} =E6=8A=95=E5=BD=B1 & 8 & $ \left[ \begin{array}{ccc} h_{11} & h_{12} & h_{13}\\ h_{21} & h_{22} & h_{23}\\ h_{31} & h_{32} & h_{33} \end{array} \right] $ & \raisebox{-0.3\height}{\includegraphics[height=3D1cm]{Ch= 4_Geometric_2_1.png}}\\=20 \par\vspace{1cm} =E4=BB=BF=E5=B0=84 & 6 & $\left[ \begin{array}{ccc} a_{11} & a_{12} & t_{x}\\ a_{21} & a_{22} & t_{y}\\ 0 & 0 & 1 \end{array} \right] $ & \raisebox{-0.3\height}{\includegraphics[height=3D1cm]{Ch= 4_Geometric_2_2.png}} \\=20 \par\vspace{1cm} =E7=9B=B8=E4=BC=BC & 4 & $\left[ \begin{array}{ccc} sr_{11} & sr_{12} & t_{x}\\ sr_{21} & sr_{22} & t_{y}\\ 0 & 0 & 1 \end{array} \right] $ &\raisebox{-0.3\height} {\includegraphics[height=3D1cm]{Ch= 4_Geometric_2_3.png}}\\=20 \par\vspace{1cm} =E6=AD=90=E5=B9=BE=E9=87=8C=E5=BE=97 & 3 & $\left[ \begin{array}{ccc} r_{11} & r_{12} & t_{x}\\ r_{21} & r_{22} & t_{y}\\ 0 & 0 & 1 \end{array} \right] $ & \raisebox{-0.3\height}{\includegraphics[height=3D1cm]{Ch= 4_Geometric_2_4.png}}\\ \par\vspace{1cm} \end{tabular} \end{table} \end{document} There are 3 places you need to manipulate a bit to find the best result, ba= sed on your case. 1. \vsapce{xcm} % for row distance/space 2. [height=3Dxcm] % for figure height 3. \raisebox{-xcm} % for lowing the figure Also, for your info, you can use \usepackage{tikz} % at preamble of course \begin{tikzpicture} \draw [white](-1,0)--(1,0); % x-axis, white color is used to supress the ax= ies. \draw [white](0,-1)--(0,1)l % y-axis \draw [thick] (x1,y1)--(x2,y2)--(x3,y3)--(x4,y4); \end{tikzpicture} to plot the simple geometry without using png. (3 posters above your poster has the information.)
