如何用xltabular设置表格列宽：第1列自适应，2-5列等宽

要实现第1列自适应最长文本宽度、第2-5列固定且宽度一致的需求，可按以下步骤修改代码：

1. 修正包引用：补全所有usepackage前的反斜杠\（原代码遗漏）。
2. 计算列宽：
   • 定义长度\colonewidth，用\settowidth获取第1列最长文本的自然宽度；
   • 基于表格总宽度（\mylen=\textheight）计算第2-5列的固定宽度\colwidth，确保4列宽度均等。
3. 修改列格式：
   • 第1列采用p{\colonewidth}，保留原悬挂缩进样式，内容会在该宽度内自动换行；
   • 第2-5列使用统一的p{\colwidth}，搭配RaggedRight优化文本排版，避免溢出。

修改后的完整代码：

\documentclass{article}
\usepackage[letterpaper,margin=2.5cm]{geometry}
\usepackage{pdflscape}
\usepackage{xltabular} 
\usepackage{ragged2e}  
\usepackage{booktabs}
\usepackage{calc} % 用于计算列宽

newlength\mylen
setlength\mylen{\textheight}

% 计算列宽度
newlength\colonewidth
% 填入第1列最长的文本
\settowidth{\colonewidth}{xxxxxxx xxxxxx xxxxxxxxx xxxxxx xxxxxxxxxx xxxxxxxxxxxxx xx'sxxxxxx xxx}
newlength\colwidth
% 计算第2-5列的固定宽度，减去第1列宽度和列间距
\setlength{\colwidth}{(\mylen - \colonewidth - 4\tabcolsep)/4}

\begin{document}

\begin{landscape}
% 修改列格式：第1列自适应最长文本，第2-5列固定相同宽度

说明 #

• 需确保\settowidth中的文本是第1列实际最长的内容，若后续修改第1列文本，需同步更新此处；
• calc包用于简化宽度计算，保证第2-5列宽度完全一致；
• RaggedRight允许文本在必要时换行，避免超出列宽导致排版错乱。
