我在横向环境中使用换行文本制作这个长表。表中的第一个数据行一切正常，但一旦我开始添加第二行，我就会收到错误“额外的对齐标签已更改为 \cr”。我从正确的行复制并仅更改了内容，即我看不到如何存在额外的对齐，并且进行了检查但找不到问题所在。任何帮助都将不胜感激。

答案1
既然你希望应用于\raggedright所有单元格的内容，你不妨修改p列类型以便\raggedright自动应用。我建议你加载array和ragged2e包，然后运行
\newcolumntype{P}[1]{>{\RaggedRight}p{#1}}
在序言中。如果你这样做不是想要允许单元格中的长单词连字符，你可以运行
\newcolumntype{P}[1]{>{\raggedright\arraybackslash}p{#1}}
然后，您可以通过执行以下命令摆脱所有后续\raggedright指令（并大大简化代码）
\begin{longtable}{P{0.75in}P{0.5in}P{0.5in}P{1in}P{1.5in}P{1.5in}PO{2.5in}}
完整的 MWE（最小工作示例），它还使用了包的线条绘制宏booktabs：
\documentclass[12pt]{report}
%%\usepackage[utf8]{inputenc} % that's the default nowadays
\usepackage[landscape,letterpaper,margin=0.8in]{geometry}
\usepackage{array, % for \newcolumntype macro
ragged2e, % for \RaggedRight macro
booktabs, % for well-spaced horizontal rules
longtable} % for longtable environment
\newcolumntype{P}[1]{>{\RaggedRight}p{#1}} % disable full justification
