这是我在 Stack Exchange 上的第一个问题，我正在尝试用 LaTeX 创建带有标题的热图。我想添加一个包含标题（水平轴）\backslash{Perplexity}{Learning Rate}和一个垂直轴，以提供有关表格的更多信息。我的代码如下：
\newcommand*{\MinNumber}{0.0}%
\newcommand*{\MidNumber}{0.5} %
\newcommand*{\MaxNumber}{1.0}%
%Apply the gradient macro
\newcommand{\ApplyGradient}[1]{%
\ifdim #1 pt > \MidNumber pt
\pgfmathsetmacro{\PercentColor}{max(min(100.0*(#1 - \MidNumber)/(\MaxNumber-\MidNumber),100.0),0.00)} %
\hspace{-0.33em}\colorbox{green!\PercentColor!yellow}{#1}
\else
\pgfmathsetmacro{\PercentColor}{max(min(100.0*(\MidNumber - #1)/(\MidNumber-\MinNumber),100.0),0.00)} %
\hspace{-0.33em}\colorbox{red!\PercentColor!yellow}{#1}
\fi
}
\newcolumntype{R}{>{\collectcell\ApplyGradient}c<{\endcollectcell}}
\renewcommand{\arraystretch}{0}
\setlength{\fboxsep}{3mm} % box size
\setlength{\tabcolsep}{0pt}
\begin{table}[H]
\begin{tabular}{*{11}{R}}

您需要做的就是使用 来\multicolumn告诉 LaTeX 这些不是R类型单元格。另请注意，slahsbox 已弃用。请不要在此网站上使用 urgent。
