我正在努力让表格的副标题适合表格的指定边距。当句子不太长时，一切都很有效，格式也很好。欢迎提出任何建议。请注意，我无法以任何方式更改标题内容。
代码：
%*** The Summary table **********************************************
\begin{tabularx}{1\linewidth}{|X|}
\hline%=============================================================
\SumHead{Title of the project}\\
\hline%=============================================================
Development of a Hybrid Brushless Exciter for the Field Supply of a Grid-Connected Wound-Rotor Wind Generator.\\
\hline%=============================================================
\SumHead{Objectives}\\

To conduct an analysis by means of basic analytical analysis and Ansys Maxwell finite element analysis. Additionally, to design the windings of a partly constructed brushless hybrid exciter, and to construct and test the design. Finally, to ensure that there is an improvement upon the current design.\\

我注意到我忘记包含 \SumHead 定义，附件如下：
答案1
虽然我认为\usepackage[table]{xcolor}在序言中执行并（重新）定义\SumHead为
\newcommand\SumHead[1]{\multicolumn{1}{%
|>{\cellcolor{lightgray!33}\centering\arraybackslash\bfseries}X|}{#1}}
可以满足您的格式要求，我建议您重新考虑表格的整个设计。具体来说，删除所有垂直线和大多数水平线，并得到如下结果：
\documentclass{article}
\usepackage{tabularx}
\usepackage{booktabs} % for \toprule, \midrule, \bottomrule, and \addlinespace macros
\newcolumntype{Y}{>{\bfseries\raggedright\arraybackslash}X}
\providecommand\SumHead[1]{\multicolumn{1}{@{}Y@{}}{#1}}
