给出下面的示例，scope 命令不会移动我所绘制的路径。我实现此目的的唯一方法是使用显式坐标，但使用矩阵 m 中的单元格编号会容易得多。
\documentclass[border=1cm]{standalone}
\usepackage{graphicx} % Required for inserting images
\usepackage{tikz}
\usetikzlibrary{matrix,shapes,arrows,fit,calc, automata}
\usepackage{listofitems}
\tikzset{cross/.style={cross out, draw=black, minimum size=2*(#1-\pgflinewidth), inner sep=0pt, outer sep=0pt},
%default radius will be 1pt.
cross/.default={10pt}}
\begin{document}
\begin{tikzpicture}
\matrix(m) [matrix of math nodes, nodes in empty cells, nodes={minimum size=1cm, outer sep=0pt, text height=1.5ex, text depth=.25ex}]

你可以改变画布：
\documentclass[border=1cm]{standalone}

\usepackage{listofitems}

%default radius will be 1pt.
cross/.default={10pt}}
\begin{document}
\begin{tikzpicture}
