我最初有一个tabularx运行良好的设置，其中包括 3 个tabular表，每个表代表一个长列。
但是，现在表格很长，必须跨越多页，所以我需要一个longtable。出于长度的考虑，我不想提供tabularx有效的设置。
这是我的代码：
\documentclass[12pt]{report}
\usepackage{array,ltablex,makecell}% ltablex loads tabularx and longtable also
\renewcommand\theadfont{\normalsize\bfseries}
% \renewcommand*\descriptionlabel[1]{\hspace\leftmargin$#1$}%This is for descriptions to appear on the LHS with an indent
\usepackage[]{multirow}%Essential for cells in table spanning multiple rows
\usepackage[autostyle]{csquotes}% This is for quotes
% \usepackage{tabulary}% This is for tables
\usepackage{ragged2e}% This is formatting for long tables
\usepackage[font={small}]{caption}
\newcolumntype{L}[1]{>{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}%This is a wrapper to make everything a certain width -left aligned columns with stuff at the top.
\newcolumntype{U}{>{\raggedright\arraybackslash\hspace{0pt}}X}%This is a wrapper to make everything a certain width -left aligned columns with stuff at the top.
\newcolumntype{C}[1]{>{\centering\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}%C is for central aligned columns and middle aligned, p puts stuff at the bottom, m middles everything.
\newcolumntype{Y}{>{\centering\arraybackslash\hspace{0pt}}X}%C is for central aligned columns and middle aligned.
\newcolumntype{R}[1]{>{\raggedleft\let\newline\\\arraybackslash\hspace{0pt}}m{#1}}
% \newcommand{\specialcell}[2][c]{\begin{tabular}[#1]{@{}c@{}}#2\end{tabular}}%This is to force new lines in cells
\usepackage{hhline}%
\usepackage[table, svgnames]{xcolor}%
\usepackage{graphicx}% This is for images
\usepackage{booktabs,dcolumn,caption}
\newcommand{\ra}[1]{\renewcommand{\arraystretch}{#1}}%This is for precision tables per property
% \captionsetup{labelsep=newline,singlelinecheck=false} % optional, this makes the caption numbers appear on a new line.

在第一个结束时multicolumn。我在这里做错了什么？我尝试multirow使用固定的 4cm 间隙和 25 行，但仍然出现相同的错误。
原始表格tabularx如下：
答案1
在这个答案中，我给出了问题的解决方案，但也给出了另一种方法，在我看来，这种方法不仅看起来更好，而且更可定制和可维护。替代方法位于问题解决方案下方
有问题的表
出现此错误的原因是，\catcode`_=13在 内设置了longtable，因此其范围仅对单行有效。我已将此代码移出 ，longtable并在其周围添加了花括号，并 以longtable限制此范围。
当您使用\multicolumn并设置在其中添加大量文本时，内容将被视为单个单元格，因此longtable无法显示内容，因为它无法打破单元格，只能打破行。
进一步的建议
- 使用-package
\endhead中的及其朋友longtable使每一页都有相同的页眉和页脚。 - 打印变量时，例如，使用或
consumer_price_index将其设置为等宽字体。\ttfamily\texttt - 使用 -package使连字符成为
_可能underscore。有多种替代方案。 - 在行之间留出更多空间以提高可读性，尤其是对于这些长变量。
- 确保只使用您知道其效果的代码。对于您的列说明符，您似乎对 做了一些不必要的事情
\let\newline\\\arraybackslash。谁给您的代码？ - 在注释代码时，请确保不要写出明显错误或至少非常多余的内容。
tabulary是用于表格的，是的，但它实际上有什么用呢？您不需要它用于表格，注释只会让您和阅读您代码的每个人都感到困惑。

替代方法
根据我的理解，您只需要一些变量或属性的列表。因此，列表比表格更合适，表格更适合比较和区分信息，而不是列出信息。因此，我建议使用itemize名为 的经过修改的环境propertyList。它应该是高度可修改的。您可以使用 -package 轻松调整所需的列数、间距、字体等enumitem。
