我被环境中一个非常奇怪的问题困住了longtable。我试图使用命令设置列宽p{width}。实际上，它适用于除第三列之外的每一列。显然，LateX 似乎完全忽略了该特定列的命令，而其他列的一切都运行顺利。下面您可以找到我正在使用的代码：

\usepackage{tabularx, array}
\usepackage{subfigure}
\usepackage{bigstrut}

\usepackage{hyperref}
\usepackage{latexsym}
\usepackage[table]{xcolor}

\usepackage{longtable}
\begin{document}

\begin{longtable}{p{10pt} p{100pt} p{10pt} p{100pt} p{10pt} p{100pt}}

为了简单起见，我将表格中的行数从 7 减少到 60，但概念保持不变。有人知道为什么似乎无法调整第三列的大小吗？
先感谢您
答案1
第三列太宽，因为前三列太窄
...——接上页。
在这种情况下，5 列就足够了。
