为什么我的内容不在表格的中心，我使用的是 \multicolumn{5}{c}{\textbf{Bootstrap}}

Question

如何让一个单词位于几行的中心？

在下面的作品中，我希望我的单词Bootstrap位于中心。它似乎位于左侧。

我用了：

\multicolumn{5}{c}{\textbf{Bootstrap}}

Answer 1

您定义了八列，但多列行中的列数只有七列。如果添加，&则正确。将“RaggedRight”重定向到 -column c（如在列定义中所做的那样）是没有意义的。如果您不需要多行列（参见示例 1），则可以使用X-column（参见示例 2）或使用 -columns ：l

示例 1

这里我已将您的代码简化为 MWE。我假设您希望X成为参差不齐的右列，因此我将一l列作为第 1 列：

\documentclass[12pt,oneside]{book}
\usepackage[showframe]{geometry}
\usepackage{makecell, multirow, tabularx}
\usepackage{booktabs, ragged2e} % Use booktabs rules and get rid of vertical rules, ragged2e to ragged text

\begin{document}

\begin{table}[h!]
\centering
\begin{tabularx}{\textwidth}{l>{\RaggedRight\arraybackslash}Xcccccc}
\toprule
& & & \multicolumn{5}{@{}c@{}}{\textbf{Bootstrap}} \\   %% Wrong number of columns, and you can extend the mlticol and extend the cmidrile to cover six columns
\cmidrule(l){4-8}
    & 
    &  \multirow{4.5}{*}{\textbf{Mean}} 
    &  \multirow{4.5}{*}{\textbf{Bias}} 
    & \multirow{4.5}{*}{\makecell{\textbf{Std.}\\ \textbf{Error}}}  
    & \multirow{4.5}{*}{\makecell{\textbf{Sig.}\\ \textbf{(2-tailed)}}}
    & \multicolumn{2}{>{\centering\arraybackslash}p{8em}}{\textbf{95\% Confidence Interval of the Difference}}  
    \\
\cmidrule(l){7-8}  %\cmidrule(lr){3-4}
     & & & & & & \multicolumn{1}{c}{\textbf{Lower}} &  \multicolumn{1}{c}{\textbf{Upper}} \\
\midrule
    Pair 1 
    & \textit{Testing example dataset} (AA) -- \textit{Testing puree Example Dataset} (BB) 
    & 44.76\% 
    &  0.19\%  
    & 4.35 
    & 0.001 
    & 36.67\% 
    & 53.33\%\\
    \bottomrule
\end{tabularx}
\end{table}
