整个文本宽度的 TikZ 矩阵

Question

我尝试创建这样的 TikZ 矩阵：

其中两行的高度约为 3 厘米。第 2 行第 1 列被规划为类似多列的形式。
但首先，我遇到了第 1 行最后一列的问题。

我只得到：

我该如何正确设置措施？

顺便说一句：对于其他一些东西，我需要如图所示的坐标，所以我认为使用 TikZ 矩阵并不是坏主意。

Answer 1

它必须是3*\pgflinewidth而不是4*\pgflinewidth。为什么是 3？因为 2 太少而 4 太多。 ;-) 好吧，更严重的是，只有 50% 的线宽在节点内。因此有两个错误朝着相反的方向发展。你似乎没有考虑到外边界，所以你应该放6*\pgflinewidth，但你只需要 50% 就使其成为3*\pgflinewidth。除此之外，如果你设置了文本深度并希望获得特定的目标高度，你还需要设置文本高度。
