看一下这个lineno包。我经常使用它，如下所示：
% number the lines
\usepackage{lineno,xcolor}
% Running line numbers:
\linenumbers
\setlength\linenumbersep{5pt}
\renewcommand\linenumberfont{\normalfont\tiny\sffamily\color{gray}}
% Same, but that reset on every page:
%\pagewiselinenumbers
% Number only every 5:th line:
%\modulolinenumbers[5]
