将元素周期表摘录的数据正确放置在 TikZ 矩阵中

Question

我有一段来自元素周期表的小摘录。

现在我想将符号（第 2 列）正确地放置在具有 8 行 18 列的 TikZ 矩阵中；其中未占用的单元格应保持空白。

对于我所说的：

\pgfmathsetglobalmacro\PeriodGroupTest{
\PeriodNo==\Row && \GroupNo==\Col ?  1 : 0  }

不知何故，使用我的方法，只有第一个条目是正确的。我做错了什么？

顺便说一句：随着测试数据的列出，它总是比任何纸张尺寸都大，所以我不得不为文档和字体大小设置奇怪的值。

\begin{filecontents}[overwrite]{psetest.csv}
Z; Symbol; Period; Group
1; H; 1; 1
2; He; 1; 18
4; Be; 2; 2
\end{filecontents}

\usepackage[margin=1mm, landscape, showframe=false]{geometry}
\usepackage{lmodern}

或许是这样的：

\begin{filecontents}[overwrite]{psetest.csv}
Z; Symbol; Period; Group
1; H; 1; 1
2; He; 1; 18
%3; Li; 2; 1
4; Be; 2; 2
% ...
14; Si; 3; 14
\end{filecontents}
