我在计算 a 的宽度longtable并在表格中使用它时遇到了麻烦。这个网站提供了几个建议，我已经实施了其中一个。但是，由于范围或由于 的一些细微差别longtable，这个\global\advance\variable技巧无法正常工作。
以下是我当前的输出。注释应该延伸到最后一列。
这是生成上图的代码。我意识到使用newenvironment和有几种技巧可以变得更加复杂newcolumntype，但出于调试的目的，我接近裸机。此侧的先前问题和答案帮助清理了表格，命令\rulefiller就是这样做的结果。

我遗漏了什么？我相信变量的作用域处理得当\global。我唯一的猜测是环境没有以与和技巧longtable兼容的方式进行处理。\newsavebox\advance
答案1
嗯，您的示例已经“接近裸机”了。您为什么要添加所有颜色命令以及大量的列和行？除此之外：longtable 将列的宽度保存在辅助文件中。因此，您可以简单地从那里检索它们（在第二次编译时）。
（下面的代码已被修改 - 添加了两个更复杂的例子，一个演示了所需的输出，另一个实现了提出的解决方案，但不起作用。）
