我有以下 MWE：

\usepackage{csvsimple}
\usepackage{filecontents}
\usepackage{longtable}
\usepackage[table]{xcolor}
\renewcommand{\rmdefault}{ptm}
\begin{filecontents*}{test.csv}

其结果如下：
但是，我需要如下图所示的内容。我不知道如何根据单元格的行号和列号来创建它。我该如何最好地做到这一点（希望能够使用 csvsimple 来实现）？
答案1
我根据 TeXnician 的评论修改了这个答案。之前我没有答案，只有一个建议。为了表明建议确实实现了预期结果，下面是使用该datatool包的代码。也许可以用 来完成这样的事情csvsimple，但正如 TeXnician 正确指出的那样， 中的“简单”csvsimple让我怀疑它不能。
注意：在下面的代码中，test.csv与上面的示例相同，只是\,其中带有的单元格放在引号中，以便可以将它们作为csv文件的一部分读取。
