\end{table}  
\end{document} 

错误

标有“Boosting the Title”的第二个表格左对齐，而不是像 Bagging Table 那样居中。

Answer 1

像这样？

使用article文档类姆韦是：

\documentclass{article}

    \begin{document}
    \centering      % <---
    \begin{table}
        \caption{The confusion tables for Subject 1}
    %\hline\hline % works only inside tabular ; inserts double horizontal lines
    \begin{tabular}{c c  c c  c c} % centered columns (6! not 4 columns)
    \multicolumn{6}{c}{Bagging}     \\
    \hline\hline %inserts double horizontal lines
    Predicted \textbackslash Actual
        & Speed 1 &  Speed 2 &  Speed 3 & Speed 4 & Speed 5 \\ [0.5ex] % inserts table
    %heading
    \hline % inserts single horizontal line
    Speed 1 & 24 & 0 & 0 & 0 & 0 \\ % inserting body of the table
    Speed 2 & 0 & 25 & 0 & 1 & 0 \\
    Speed 3 & 0 & 0 & 25 & 0 & 0 \\
    Speed 4 & 0 & 0 & 0 & 24 & 0\\
    Speed 5 & 1 & 0 & 0 & 0 & 25 \\ [1ex] % [1ex] adds vertical space
    \hline\hline %inserts single line
    \multicolumn{6}{c}{Boostingm}\\
    \hline\hline %inserts single line
    Predicted \textbackslash Actual  & Speed 1 &  Speed 2 &  Speed 3 & Speed 4 &
    Speed 5 \\ [0.5ex] % inserts table
    %heading
    \hline % inserts single horizontal line
    Speed 1 & 22 & 0 & 0 & 0 & 0 \\ % inserting body of the table
    Speed 2 & 0 & 25 & 0 & 1 & 0 \\
    Speed 3 & 3 & 0 & 24 & 0 & 0 \\
    Speed 4 & 0 & 0 & 0 & 23 & 0\\
    Speed 5 & 0 & 0 & 1 & 0 & 24 \\ [1ex] % [1ex] adds vertical space
    \hline %inserts single line
  \end{tabular}
\label{table:S1_confusion_table} % is used to refer this table in the text
\end{table}
\end{document}

\hline不应该在外面tabular。为了使“标题”居中，您应该使用\multicolumn环境。

编辑： 我将借助以下包来设计您的表格booktbs：

\documentclass{article}
\usepackage{booktabs}

\begin{document}
    \begin{table}
    \centering
    \renewcommand\arraystretch{1.2}
        \caption{The confusion tables for Subject 1}
    \begin{tabular}{c c  c c  c c} % centered columns (6! not 4 columns)
        \toprule
    \multicolumn{6}{c}{Bagging}     \\
        \midrule
    Predicted \textbackslash Actual
        & Speed 1 &  Speed 2 &  Speed 3 & Speed 4 & Speed 5 \\ 
    %heading
    \hline % inserts single horizontal line
    Speed 1 & 24 &  0 &  0 &  0 &  0 \\ 
    Speed 2 &  0 & 25 &  0 &  1 &  0 \\
    Speed 3 &  0 &  0 & 25 &  0 &  0 \\
    Speed 4 &  0 &  0 &  0 & 24 &  0 \\
    Speed 5 &  1 &  0 &  0 &  0 & 25 \\ 
        \midrule
    \multicolumn{6}{c}{Boostingm}\\
        \midrule
    Predicted \textbackslash Actual  & Speed 1 &  Speed 2 &  Speed 3 & Speed 4 &
    Speed 5 \\ [0.5ex] % inserts table
    %heading
        \midrule 
    Speed 1 & 22 &  0 &  0 &  0 &  0 \\ % inserting body of the table
    Speed 2 &  0 & 25 &  0 &  1 &  0 \\
    Speed 3 &  3 &  0 & 24 &  0 &  0 \\
    Speed 4 &  0 &  0 &  0 & 23 &  0\\
    Speed 5 &  0 &  0 &  1 &  0 & 24 \\ 
        \bottomrule
  \end{tabular}
\label{table:S1_confusion_table} % is used to refer this table in the text
\end{table}
\end{document}

这使：
