tikz 矩阵中的边距问题

Question

我正在制作一款方形棋盘游戏，需要旋转单元格中的文本（以便所有玩家都能阅读）。我遇到的问题是，当我旋转单元格时，会出现一些额外的空格，我无法消除这些空格。正如本网站其他答案所建议的那样，我使用了

anchor=base,minimum width=1.75cm,minimum height=1.75cm,text height=2ex,text depth=0.25ex

和

column sep=0cm, row sep=0cm, outer sep=0pt,inner sep=0

它应该在它应该在的地方。但我仍然得到错误。我的代码是：

\documentclass{standalone}

\usetikzlibrary{calc,matrix}
\usepackage{amsthm}
\usepackage{colortbl}
\begin{document}

我的输出：

我怎样才能除掉所有空白处，以便旋转不会弄乱我的板子？

Answer 1

基本问题的解决方案如下西格尔 注释。但是，可以通过以下方式简化代码，使其更加简洁：

• 为每一列分别定义样式。这样，所有用于旋转的本地命令和许多用于颜色的命令都变得多余
• 最好在一个地方定义节点样式，作为选项matrix
• 由于节点的内容是数字，因此规定 text depth多余的
• 为节点的平方足以确定节点的最小尺寸

得到的 mwe 为：

免责声明：Sigur 解决了这个问题，功不可没。我所做的只是做了一些额外的小调整。anchor=center正如 Sigur 所指出的，主要问题通过设置来解决，否则旋转中心会不一样。代码中标记了小改动。
