如何在 tikz 矩阵中排列列标题？

Question

我试图让列标题与\shortstack{}单元格中的内容相匹配。我希望顶行相同，而我能尝试使其相同的唯一方法是使用 \rule 引入假间距，但我确信这不是最好的方法。有人能帮我将矩阵中标题行的顶行对齐吗？

请帮我将第一行（所有三列）的顶线对齐

Answer 1

让我扩展我的评论来回答：

• 答案仅关注矩阵，因此序言仅减少到必要的库matrix
• 单元格的宽度由 预先确定text width=7em，如果需要，可以通过在 中添加选项来分别适应每一列matrix，例如：

column 2/.append style = {nodes={text width=6ex}}

• 第一行的高度由 手动确定row 1/.append style = {nodes={minimum height=3\baselineskip}}。

Answer 2

添加如下内容：

nodes={draw,inner sep=5pt,font=\sffamily,inner xsep=5pt,
%inner sep=0pt,   outer sep=0pt,
%minimum width=1.9em,
% New: 
text height=4\ht\strutbox,
text depth=\dp\strutbox,
text width =11\ht\strutbox,
align=center,
},
