在长表中强制旋转标题内换行

Question

我正在尝试构建一个带有两行标题的表格。标题内的文本很长，所以我正在旋转并希望像这样拆分其中一个较长的标题。当前代码生成下图。并且 \newline 命令似乎不起作用

\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\usepackage{array}

\newcolumntype{R}[1]{>{\raggedleft\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}

Answer 1

这是一个解决方案makecell（简化旋转单元格的代码）和\pbox（工作原理类似\parbox，除了指定的宽度是 最大限度价值）：

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{fancyhdr}
\usepackage{array}
\usepackage{float}
\usepackage{rotating}
\usepackage{longtable}
\usepackage{makecell}
\renewcommand{\theadfont}{\normalsize}
\usepackage{pbox}
\usepackage{setspace}
\usepackage{xcolor}

\newcolumntype{R}[1]{>{\centering\arraybackslash}p{#1}}

\begin{document}

\section{Introduction}
\setlength{\rotheadsize}{1.1in}
\setlength{\extrarowheight}{2pt}
    \begin{longtable}{l|R{0.4in}R{0.3in}|R{0.4in}R{0.2in}R{0.3in}R{0.4in}|R{0.3in}R{0.2in}R{0.4in}R{0.3in}}
    \caption{GCSE uptake} \\
      \hline
      & \multicolumn{2}{c}{Population} & \multicolumn{4}{c}{Subject reach} & \multicolumn{4}{c}{Subject actual} \\%
