我使用 pgfplots 制作了热图。但单元格中的数字未垂直居中对齐。我如何将它们居中对齐，或者如何在底部添加填充以使它们出现在中心。

答案1
这是比较难的方法。你可以装载adjustbox包裹，将电池内容放入箱子中，然后抬起内容。
\usepackage{adjustbox}
在\pgfplotstabletypeset选项中输入
postproc cell content/.append style={
/pgfplots/table/@cell content/.add={\begin{adjustbox}{raise=1.25ex}}{\end{adjustbox}}},
适当调整1.25ex。
