我是 LaTeX 的新手，我正在尝试将我的表格转换为 Excel2Latex。
这是我的乳胶文档：
\documentclass[a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{multirow}
\usepackage{float}
\usepackage{tabularx}
\begin{document}
\begin{table}[htbp]
\centering
\caption{Add caption}
\begin{tabularx}{\textwidth}{lrrr}
\hline

\label{tab:addlabel}%
\end{table}%
\end{document}
但不幸的是，正如你所见，它超出了页面的右边距
- 我该如何修复？
答案1
- 如果使用
tabularx至少一个列类型应该是X类型（或其衍生物） \multicolumn{1}{p{25.355em}{ ... long text ...}太宽。删除此命令并为此列使用X列类型- 删除所有
\mullticolumn{1}{l}{...}。它们只是杂乱无章。而是相应地设置列类型（从r到l） - 我会删除大部分水平线
- 对于主要的，我将使用
booktabs包中定义的规则
\documentclass[a4paper]{article}
\usepackage{ragged2e}
\usepackage{booktabs, makecell, tabularx}
\newcolumntype{L}{>{\RaggedRight\hspace{0pt}}X}
%---------------- show page layout. don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%

附录： 考虑到@Barbara Beeton 的评论，上述 MWE 可以重新设计如下：
\documentclass[a4paper]{article}
