将标题置于表格下方中央

我有一张有 2 列 12 行的表格。我需要表格显示在页面的左侧（我可以做到），但是标题位于页面的中央。我想将标题放在表格下方，并使其位于表格下方的中央。输出如下所示。在此处输入图片描述

\documentclass[12pt,english]{article}
\usepackage{caption}
\begin{document}
 \begin{table}[H]
 \begin{tabular}{|c|>{\centering}p{2cm}|}
 \hline 
  Year & Population (millions)\tabularnewline
  \hline 
   $1900$ & $1650$\tabularnewline
   $1910$ & $1750$\tabularnewline
   $1920$ & $1860$\tabularnewline
   $1930$ & $2070$\tabularnewline
   $1940$ & $2300$\tabularnewline
   $1950$ & $2560$\tabularnewline
   $1960$ & $3040$\tabularnewline
   $1970$ & $3710$\tabularnewline
   $1980$ & $4450$\tabularnewline
   $1990$ & $5280$\tabularnewline
   $2000$ & $6070$\tabularnewline
   \hline 
  \end{tabular}
  \raggedright{}\caption{World Population}\label{table1}
  \end{table}
 \end{document}

这里有一种方法（因为您已经想要[H]选项并且已经加载了caption包，我想这对您来说没问题）：

\documentclass[12pt,english]{article}
\usepackage{caption}
\usepackage{array}
\begin{document}
 % A \noindent is possibly needed here as @Mico suggested in his comment
 \noindent\begin{minipage}{0.35\textwidth}
 \centering
 \begin{tabular}{|c|>{\centering}p{2cm}|}
 \hline 
  Year & Population (millions)\tabularnewline
  \hline 
   $1900$ & $1650$\tabularnewline
   $1910$ & $1750$\tabularnewline
   $1920$ & $1860$\tabularnewline
   $1930$ & $2070$\tabularnewline
   $1940$ & $2300$\tabularnewline
   $1950$ & $2560$\tabularnewline
   $1960$ & $3040$\tabularnewline
   $1970$ & $3710$\tabularnewline
   $1980$ & $4450$\tabularnewline
   $1990$ & $5280$\tabularnewline
   $2000$ & $6070$\tabularnewline
   \hline 
  \end{tabular}
  \captionof{table}{World Population}\label{table1}
  \end{minipage}
 \end{document}

由于表格内容必须排版为左对齐（又称右对齐），我认为如果标题也设置为左对齐，看起来会更好。（但是，请参见下文以了解不同的解决方案。）可以通过加载带有caption选项singlelinecheck=false和的包来实现此格式化目标justification=raggedright。

\documentclass[12pt,english]{article}
\usepackage{array,caption}
\captionsetup{singlelinecheck=false,justification=raggedright}
\begin{document}
\begin{table}[ht!]
 \begin{tabular}{|c|>{\centering\arraybackslash}p{2cm}|}
 \hline 
   Year & Population (millions)\\ \hline 
   $1900$ & $1650$\\
   $1910$ & $1750$\\
   $1920$ & $1860$\\
   $1930$ & $2070$\\
   $1940$ & $2300$\\
   $1950$ & $2560$\\
   $1960$ & $3040$\\
   $1970$ & $3710$\\
   $1980$ & $4450$\\
   $1990$ & $5280$\\
   $2000$ & $6070$\\ 
 \hline 
 \end{tabular}
\caption{World Population}\label{table1}
\end{table}
\end{document}

或者，如果标题必须位于tabular材料正下方和材料tabular必须排版左对齐，我建议您（a）运行\captionsetup{justification=centering}，（b）加载三部分表包，以及 (c) 将tabular环境和\caption语句都包含在threeparttable环境中。此设置允许 LaTeX 测量tabular材料的宽度并将标题置于表格下方的中心；如果需要，LaTeX 会自动在标题中插入换行符。此行为如以下屏幕截图所示。

\documentclass[12pt,english]{article}
\usepackage{array,caption,threeparttable}
\captionsetup{justification=centering}
\begin{document}
\begin{table}[ht!]
\begin{threeparttable}
 \begin{tabular}{|c|>{\centering\arraybackslash}p{2cm}|}
 \hline 
   Year & Population (millions)\\ \hline 
   $1900$ & $1650$\\
   $1910$ & $1750$\\
   $1920$ & $1860$\\
   $1930$ & $2070$\\
   $1940$ & $2300$\\
   $1950$ & $2560$\\
   $1960$ & $3040$\\
   $1970$ & $3710$\\
   $1980$ & $4450$\\
   $1990$ & $5280$\\
   $2000$ & $6070$\\ 
 \hline 
 \end{tabular}
\caption{World Population}\label{table1}
\end{threeparttable}
\end{table}
\end{document}
