Redisplay line numbers on each page:
This method is for the double-column version (only need to delete "\switchlinenumbers % double-column" of the code for a single column), and the template Conference-LaTeX-template_7-9-18test is valid.
Use the command as follows:
\usepackage{lineno} % 这个包就是latex自带的添加行号的包了
%
% 其它引用的包
%
\begin{document} % 文章开始
%
\pagewiselinenumbers% 按页重新编号
\switchlinenumbers % 双栏
%
All page line numbers:
\usepackage{lineno}
\begin{document}
\linenumbers
