LaTeX讲解系列(4)： LaTex Preamble区中usepackage常用总结

0. 这些必须引：

   \usepackage{graphicx}
   \usepackage{amsmath}

1. 使用\cref{}时要引用\usepackage{cleveref}。而且这个命令的位置一定一定要在定义/引用所有的包的最后再import进来，不然会出现奇怪的问题(无法正常超链接等)。举个栗子，比如要在hyperref之后usepackage进来。

   % ......
   \definecolor{cvprblue}{rgb}{0.21,0.49,0.74}
   \usepackage[pagebackref,breaklinks,colorlinks,allcolors=cvprblue]{hyperref}
   
   %%%%%%%%% ADD CREF AT LAST, ESPECIALLY AFTER HYPERREF
   \usepackage{cleveref}
   % add support for algorithm env
   \crefname{algorithm}{Alg.}{Algs.}
   \Crefname{algorithm}{Alg.}{Algs.}
   
   \crefname{figure}{Fig.}{Figs.}
   \Crefname{figure}{Fig.}{Figs.}
   
   \crefname{table}{Tab.}{Tabs.}
   \Crefname{table}{Tab.}{Tabs.}
   
   \crefname{align}{Eq.}{Eqs.}
   \Crefname{align}{Eq.}{Eqs.}
   
   \crefname{equation}{Eq.}{Eqs.}
   \Crefname{equation}{Eq.}{Eqs.}

   其中\crefname和\Crefname是用于自动对相应的环境替换为自己想要的缩写的，比如引用到公式环境时替换为Eq. (编号)等。

2. 使用表格时把这几个常用的包引上：

   % This package is useful for creating more readable and organized tables by allowing flexible content formatting within cells.It allows you to:
   % Line Breaks in Cells: Use \makecell{} to create line breaks within a single cell.
   % Custom Alignment: Easily control horizontal and vertical alignment.
   % Multi-line Headers: Create complex table headers with multiple lines.
   \usepackage{makecell}
   
   
   % Underlining: Use \uline{text} for a single underline.
   % Double Underlining: Use \uuline{text} for a double underline.
   %Strikethrough: Use \sout{text} for a strikethrough.
   % Wave Underline: Use \uwave{text} for a wavy underline.
   % 比如表格里比较Performance的时候，最好的结果加粗，第二好的结果下划线。
   \usepackage[normalem]{ulem}
   
   
   % supertabular:Allows tables to span multiple pages.Usage: Similar to the standard tabular environment, but can handle longer tables that need to continue onto subsequent pages.
   % booktabs:Provides enhanced table rules (lines) for professional-quality tables. Offers commands like \toprule, \midrule, and \bottomrule for creating aesthetically pleasing horizontal lines without vertical lines, following typesetting rules for better readability.
   \usepackage{supertabular,booktabs}
