algorithm2e - 使最顶部和底部的水平线更粗

Question

我对上面的输出非常满意，但希望顶部和底部的水平线更粗一些。有什么帮助吗？

Answer 1

以下长度名称似乎控制规则高度：

\setlength\algoheightrule{<height>}        % The upper and the lower rules
\setlength\algotitleheightrule{<height>} % The rule between a title and code

如果要恢复默认长度，请运行以下命令

\setlength\algoheightrule{\algoheightruledefault} 
\setlength\algotitleheightrule{\algotitleheightruledefault}

这个例子：

\documentclass{article}
\usepackage[ruled]{algorithm2e}

\setlength\algoheightrule{2pt}        % Upper and lower rules
\setlength\algotitleheightrule{1.2pt} % Rule below the title
