如何设置行标题的间距以及子表标题的位置

Question

我一直在尝试使用 pdfLatex 构建 3x3 混淆矩阵。到目前为止，我的输出以及代码都包含在下图中。

我对矩阵的两个方面感到困惑。

首先，我需要增加“实际值”与矩阵边缘的“左”、“右”和“直”行标题之间的空间，但到目前为止我还无法做到正确。

其次，我需要将第二个矩阵底部的子标题“（b）第 2 部分”向左移动，使其与矩阵的中间行对齐，就像子标题“（a）第 1 部分”对第一个矩阵的作用一样。

我该如何进行上述两个修复？

我已尝试尽可能地整理代码。我是个新手，因此可能没有使用最佳方法。如有任何关于改进的进一步建议，我将不胜感激。

谢谢。

Answer 1

以下是其中一个子表的更简单代码。希望它能满足您的要求：

\documentclass{article}
\usepackage{subcaption}
\usepackage{rotating, multirow}
\usepackage{graphicx}
\newcommand{\MyBox}[1]{{\parbox[c][1.4cm][c]{1.1cm}{#1}}}
\newcommand{\rotbox}[1]{ \rotatebox[origin = c]{90}{\makebox[0pt]{\bfseries#1}}}

\begin{document}

\begin{table}[h!]
\centering
\caption{Confusion Matrix}
\label{tab:table1}
\begin{subtable}{0.49\linewidth}
    \begin{tabular}{c@{\enspace }c|c|c|c|}
        \multicolumn{2}{c}{} & \multicolumn{3}{c}{\bfseries Prediction outcome} \\
        \multicolumn{2}{c}{} & \multicolumn{1}{c}{\textbf{Left}} & \multicolumn{1}{c}{\makebox[0pt]{\textbf{Straight}}} & \multicolumn{1}{c}{\textbf{Right}}\\[0.5ex]
\cline{3-5}
    & \rotbox{Left} & \MyBox{0} & \MyBox{1} & \MyBox{2} \\
\cline{3-5}
 \rotbox{Actual value} & \rotbox{Straight} & \MyBox{0} & \MyBox{1} & \MyBox{2} \\
\cline{3-5}
    & \rotbox{Right} & \MyBox{0} & \MyBox{1} & \MyBox{2} \\
\cline{3-5}
    \end{tabular}
    \caption{Part 1}
\end{subtable}
\end{table}
