我应该何时使用环境tabbing？每当我想要排列东西时，我都会使用tabular，但我隐约担心我有时会错过更简单的解决方案，因为我不会从 的角度思考tabbing。
答案1
以下内容或许可以解释何时使用哪种方法：
tabular创建一个牢不可破的块，同时tabbing可以跨越页面边界打破。tabular允许使用列规范创建特定的对齐，同时tabbing假定所有选项卡都是l左对齐的。tabular可以插入跨越内容宽度的垂直和水平规则，而使用 则很难做到这一点tabbing。tabular可以使内容按照paragraph 列规范换行，而tabbing不允许这样做。
tabular下面是一个小例子，展示了对齐tabbing和分页之间的几个区别（也许是最显着的区别） ：
\documentclass{article}
\usepackage[paperheight=25\baselineskip,margin=1in]{geometry}% Just for this example
\begin{document}
\section{A section}
