但它会产生一个错误：
失控参数？（pic cs：start1）+（0pt，2ex）$）矩形（$（pic cs：end1）+（0pt，-\ETC。！段落在\tikz@parse@calculator 完成之前结束。\par l.199
我怀疑你忘记了一个“}”，导致我将这个控制序列应用于太多文本。我们怎样才能恢复？我的计划是忘记整件事并希望得到最好的结果。）
类似的代码在 beamer 中运行良好。
任何帮助都将不胜感激。谢谢。亚历克斯。

为了使$tikz 坐标中的符号（如 的定义\ShadeCell）起作用，您需要加载calc库：
\usepackage{tikz}
\usetikzlibrary{calc}%%% add this line
