关注此问题以编程方式定义矩阵节点，我能够更精确地说明我想要实现的目标。抱歉，我在第一个问题中回答得太笼统了。这是新的 MWE。阅读第一个问题 (这里) 是绝对必要的。
我的最终目标是在矩阵中定义节点定位，节点之间的距离并不相同。
我能够使用方法 1 定义具有附加样式的每个节点的尺寸，但希望使用方法 2 或 3（或类似方法）来实现。出于某种原因，循环无法正常用于附加样式：也许我需要在某处缓冲信息？

对于方法 2，正如 @jfbu 在其评论中所建议的，您需要强制扩展row \row\space column \col，为此您只需添加/.expanded，如下所示：
% Method 2 : Append style and loop with xintFor
\xintForpair #1#2 in {(1,dimensionsBigBox), (2,dimensionsSmallBox), (3,dimensionsBigBox),(4,dimensionsSmallBox), (5,dimensionsSmallBox), (6,dimensionsSmallBox), (7,dimensionsBigBox), (8,dimensionsBigBox), (9,dimensionsBigBox)} \do {
%Set style #2 for node #1 \\
\pgfmathsetmacro\row{int(div(#1-1,3)+1)}
\pgfmathsetmacro\col{int(mod(#1-1,3)+1)}
\tikzset{mygridmatrix/.append style/.expanded={row \row\space column \col/.style={nodes={#2}}}}
}
要像方法 3 中那样使用foreach循环，您可以将样式保存在临时变量中并将其设置在循环之外，如下所示：
% Method 3 : Append style and loop with foreach
\xdef\temp{}
\foreach[count=\x from 0] \y in {dimensionsBigBox,dimensionsBigBox,dimensionsBigBox,dimensionsSmallBox,dimensionsSmallBox,dimensionsSmallBox,dimensionsBigBox,dimensionsBigBox,dimensionsBigBox}{
%Set style \y for node \x
\pgfmathsetmacro\row{int(div(\x,3)+1)}
\pgfmathsetmacro\col{int(mod(\x,3)+1)}
\xdef\temp{\temp,row \row\space column \col/.style={\y}}
}
\tikzset{mygridmatrix/.append style/.expanded={\temp}}
完整代码如下：

这似乎是一场漫长的对话。;-) 这是另一次尝试。您只需使用\xintForpair新列表运行，就会得到一个不同的矩阵。
\documentclass[border=2mm,tikz]{standalone}
\usetikzlibrary{matrix}

\tikzset{dimensionsBigBox/.style={

text depth=0.5em, text height=1em,
}}
\tikzset{dimensionsSmallBox/.style={
minimum height=1cm,
rectangle,
fill=none, draw=red,
text depth=0.5em, text height=1em,
}}
\tikzset{
mygridmatrix/.style={
matrix of nodes,
row sep=-\pgflinewidth, column sep=-\pgflinewidth,
nodes={draw},
nodes in empty cells,
},
}
\xintForpair #1#2 in {(1,dimensionsBigBox), (2,dimensionsSmallBox), (3,dimensionsBigBox),(4,dimensionsSmallBox), (5,dimensionsSmallBox), (6,dimensionsSmallBox), (7,dimensionsBigBox), (8,dimensionsBigBox), (9,dimensionsBigBox)} \do {
%Set style #2 for node #1 \\
\pgfmathsetmacro\row{int(div(#1-1,3)+1)}
\pgfmathsetmacro\col{int(mod(#1-1,3)+1)}
\tikzset{mygridmatrix-\row-\col/.style={#2}}
}
\begin{tikzpicture}[every node/.append style={minimum width=6mm}]
\matrix[matrix of nodes] (m) {%
|[mygridmatrix-1-1,alias=topleft]|& |[mygridmatrix-1-2]| &|[mygridmatrix-1-3]|\\
|[mygridmatrix-2-1]|& |[mygridmatrix-2-2]| &|[mygridmatrix-2-3]|\\
