我正在尝试使用 pgfmatrix 表示关系表，如这前一个例子但是，这种方法存在以下错误：
包 pgf 错误：您还不能嵌套 pgfmatrix 环境。001 & \matrix at (10,0) (m2) {
对于我来说，这个功能是必需的，因为我想表示嵌套的关系模型，因此应该能够像这个 MWE 中那样定义一些东西（编辑）同时保留主键和外键箭头，如上述示例所示：
\documentclass[tikz]{standalone}
\begin{document}
\begin{tikzpicture}
\matrix (m1) {
id & table \\
001 & \matrix at (10,0) (m2) {
id & date \\
100 & 30-Dic-2016 \\
}; \\
};
\end{tikzpicture}
\end{document}
有没有其他方法可以产生相同的表示，或者更好的是，有没有办法欺骗 tikz 有效地嵌套这两个部分？提前致谢。

没有 TiKz 的预期效果：

答案1
以下是使用我们在评论中讨论的方法的示例。它用于tikzmark在表格中放置标记，然后使用 注释表格tikzpicture。
我不确定product key和foreign key注释在这里如何应用，因为这些链接列在不同的表格中具有相同的数据，这不适用于这里。所以我展示了如何在链接示例中使用来做其他几件事tikzmark，并编造了一些有点像的product/foreign key东西。基本上，如果您决定这样做，这应该足以让您根据自己的需要定制方法。
该方法需要两次编译运行。第一次运行时，在大多数情况下，注释看起来会一团糟，或者在其他情况下根本不会显示。这是因为 TeX 还不知道它们应该放在哪里。所以它们只是去某个任意的地方，通常是一个在另一个之上。第二次运行时，一切都稳定下来，您可以查看是否真的需要调整任何东西等等。
就 TeX 而言，叠加的注释不占用空间，因此您必须确保在页面上留出足够的空间。出于这个原因，我已将示例更改为使用类article。[但请参阅下面的编辑以了解基于的方法standalone。]
我也尝试过对表格代码进行一些清理和简化。但请注意，人们普遍认为垂直规则是邪恶的，而所有行的水平规则则被认为以几乎同样的力度追求印刷邪恶。彩色行和单元格也好不到哪里去，尤其是与规则结合使用时。（但如果你已经有了垂直规则，我想你最好把事情做好。谁想犯印刷错误？为羊绞死可能和为羔羊绞死一样糟糕……）
\sffamily \texttt{all of the text in the current scope}请注意，写或说完全没有任何意义>{\raggedright}c。在第一种情况下，您要么想要 sans 字体，要么想要 typewriter 字体：您不能同时拥有两者。在第二种情况下，您要么想要文本向右倾斜，要么想要文本居中：您不能同时拥有两者。
注释行添加了带有标记名称的小红色标签。我发现这在编辑时很有用，如果我开始忘记什么在哪里，或者如果我稍后返回编辑图表并想快速弄清楚我目前得到了什么。

答案2
矩阵不能嵌套tikz，但可以重叠。
矩阵是节点，可以相对于另一个矩阵的单元格（也是一个节点）进行定位tikz matrix。
如果您需要引用节点单元，则必须创建它，即使它是空的（请参阅我的代码中的注释）。
