LaTeX Overleaf会议论文多图排版求助：首图边距异常过宽

我在Overleaf平台使用LaTeX制作会议论文的多图组合图时，发现首图边距明显比其他图片宽，代码如下：

\begin{figure}[!ht]
\begin{tabular}{ccccc}
%\hline
\centering
\bmvaHangBox{\fbox{\parbox{2.0cm}{~\\[0.8mm]
\rule{0pt}{1ex}\hspace{0.5mm}\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/000874.jpg}\\[-0.1pt]}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/001075.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/002478.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/002756.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/002849.jpg}}} \\
\multicolumn{5}{c}{Original Images} \\
%2nd row 
\bmvaHangBox{\fbox{\parbox{2.0cm}{~\\[0.8mm]
\rule{0pt}{1ex}\hspace{0.5mm}\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/000874.jpg}\\[-0.1pt]}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/001075.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/002478.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/002756.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/002849.jpg}}} \\
\multicolumn{5}{c}{DenseCL with 200 epochs}\\

问题原因与解决方案 #

首图边距异常是因为额外嵌套了\parbox{2.0cm}和手动添加的\hspace{0.5mm}，这些元素让首图的整体宽度超出了其他图片的尺寸。只需移除这些冗余结构，让首图和其他图片保持一致的格式即可。

修改后的代码：

\begin{figure}[!ht]
\begin{tabular}{ccccc}
%\hline
\centering
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/000874.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/001075.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/002478.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/002756.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/Original/002849.jpg}}} \\
\multicolumn{5}{c}{Original Images} \\
%2nd row 
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/000874.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/001075.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/002478.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/002756.jpg}}} &
\bmvaHangBox{\fbox{\includegraphics[width=1.8cm]{images/knet_deeplab_R/DenseCL_200/002849.jpg}}} \\
\multicolumn{5}{c}{DenseCL with 200 epochs}\\
\end{tabular}
\end{figure}

另外注意补充完整\end{tabular}和\end{figure}标签，避免编译报错。
