无法在 Latex 中并排对齐表格

Question

我正在尝试在 latex 中并排对齐表格，但我无法使用minipage。我在下面提到了使表格并排的 latex 代码

\begin{minipage}[t]{0.4\textwidth}

\begin{tabular}{l*{6}{c}r}

I32             & optimizer & Loss & PSNR  \\
\hline
      & Adam     & Mean Square Error   & 0    \\
     & Adam     & DSSIM               & 0    \\
     & Adam     & PSNR loss           & 1    \\
     & Adam     & Mean Absolute Error & 1    \\
     & Ranger   & Mean Absolute Error + Mean Gradient Error & \\
     & Ranger   & Mean Absolute Error + Mean Gradient Error + KL Loss &\\
     & Ranger   & Mean Absolute Error + KL Loss & \\
     & Ranger   & Mean Absolute Error + KL Loss + Mean Gradient Error &\\
     & Ranger21 & Mean Absolute Error & \\
     & Ranger21 & Mean Absolute Error + KL Loss & \\
     & Ranger21 & Mean Absolute Error + 0.75 KL Loss & \\
     & Ranger21 & Mean Absolute Error + 0.5 KL Loss & \\
\hline
\end{tabular}

\end{minipage}

\begin{minipage}[t]{0.4\textwidth}
\begin{tabular}{l*{6}{c}r}
I43 & optimizer & Loss & PSNR  \\
\hline
    & Adam     & Mean Square Error   & 0    \\
     & Adam     & DSSIM               & 0    \\
     & Adam     & PSNR loss           & 1    \\
     & Adam     & Mean Absolute Error & 1    \\
     & Ranger   & Mean Absolute Error + Mean Gradient Error & \\
     & Ranger   & Mean Absolute Error + Mean Gradient Error + KL Loss &\\
     & Ranger   & Mean Absolute Error + KL Loss & \\
     & Ranger   & Mean Absolute Error + KL Loss + Mean Gradient Error &\\
     & Ranger21 & Mean Absolute Error & \\
     & Ranger21 & Mean Absolute Error + KL Loss & \\
     & Ranger21 & Mean Absolute Error + 0.75 KL Loss & \\
     & Ranger21 & Mean Absolute Error + 0.5 KL Loss & \\
\hline
\end{tabular}

\end{minipage}

Answer 1

我建议使用以下两种替代布局之一，它们只使用 2 个而不是 16 个表格以及缩写（类似于 Mico 使用的在他们的回答中）

\documentclass{article}
\usepackage{booktabs}
\usepackage{geometry}

\begin{document}

Answer 2

您需要大幅简化和精简表格，才能使两个表格并排显示。以下代码给出了如何完成此操作的示例。

\documentclass{article} % or some other suitable document class
\usepackage[a4paper,margin=2.5cm]{geometry} % set page parameters suitably
\begin{document}

\noindent
\begin{tabular}[t]{ @{} llc @{} }
\multicolumn{3}{@{}l}{\textbf{I32}}\\
Optimizer & Loss & PSNR \\
\hline
Adam     & MSE        & 0   \\
Adam     & DSSIM      & 0   \\
Adam     & PSNR loss  & 1   \\
Adam     & MAE        & 1   \\
Ranger   & MAE + MGE  &     \\
Ranger   & MAE + MGE + KLL &\\
Ranger   & MAE + KLL  &     \\
Ranger   & MAE + KLL + MGE &\\
Ranger21 & MAE        &     \\
Ranger21 & MAE + KLL  &     \\
Ranger21 & MAE + 0.75 KLL & \\
Ranger21 & MAE + 0.5 KLL &  \\
\hline
\end{tabular}\hspace{\fill}
\begin{tabular}[t]{ @{} llc @{} }
\multicolumn{3}{@{}l}{\textbf{I43}}\\
Optimizer & Loss & PSNR \\
\hline
Adam     & MSE       & 0    \\
Adam     & DSSIM     & 0    \\
Adam     & PSNR loss & 1    \\
Adam     & MAE       & 1    \\
Ranger   & MAE + MGE &      \\
Ranger   & MAE + MGE + KLL &\\
Ranger   & MAE + KLL &      \\
Ranger   & MAE + KLL + MGE &\\
Ranger21 & MAE       &      \\
Ranger21 & MAE + KLL &      \\
Ranger21 & MAE + 0.75 KLL & \\
