我想创建 10x10 的正方形并用零填充周围的元素？

Question

我想创建 10x10 的正方形，并用零填充周围的元素

如附图所示

但是当我添加零时，这些元素之间就会出现一个空格。

以下是 MWE：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{matrix, backgrounds}



\newcommand{\0}{\scalebox{2}{$0$}}

\begin{document}

\begin{tikzpicture}[font=\scriptsize]
  \matrix (space) [matrix of math nodes, row sep=-\pgflinewidth, column sep=-\pgflinewidth, 
    nodes={draw, semithick, minimum height=10mm, minimum width=10mm, text=blue}]
{\0 & \0 & \0 & \0 & \0 & \0 & \0 & \0  & \0 & \0  \\ 
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\ 
 \0 &\  & \ & \ & \  &  \  & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 & \0 & \0 & \0 & \0  & \0  & \0 & \0  & \0  & \0  \\};




\end{tikzpicture}


\begin{tikzpicture}[font=\scriptsize]
  \matrix (space) [matrix of math nodes, row sep=-\pgflinewidth, column sep=-\pgflinewidth, 
    nodes={draw, semithick, minimum height=10mm, minimum width=10mm, text=blue}]
{\ & \ & \ & \ & \ & \ & \ & \  & \ & \  \\ 
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\ 
 \ &\  & \ & \ & \  &  \  & \ & \  & \  & \  \\
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\
 \ &\  & \ & \ & \  &  \ & \ & \  & \  & \  \\
 \ & \ & \ & \ & \  & \  & \ & \  & \  & \  \\};




\end{tikzpicture}

\end{document}

Answer 1

尝试此代码（您可以更改颜色和/或线宽）：

\documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
 \draw[gray!25,line width=.4pt] (0,0) grid (10,10);
 \foreach \x in {.5,1.5,...,9.5}{%
    \node at (\x,.5) () {\tiny 0};
    \node at (\x,9.5) () {\tiny 0};
    \node at (.5,\x) () {\tiny 0};
    \node at (9.5,\x) () {\tiny 0};
    };
\end{tikzpicture}
\end{document}

输出为：

编辑：如果您想要黑线、更大的“0”并且只想在四个角上写一次“0”（带有一些其他小装饰），这个代码更好：

   \documentclass[12pt]{article}
\usepackage{tikz}
\begin{document}
    \begin{tikzpicture}
        \draw[line width=.4pt] (0,0) grid (10,10);
        \foreach \x in {.5,1.5,...,9.5}{%
            \node[blue] at (\x,.5) () {\bfseries \small 0};
            \node[blue] at (\x,9.5) () {\bfseries \small 0};
        };
        \foreach \x in {1.5,...,8.5}{%
            \node[blue] at (.5,\x) () {\bfseries \small 0};
            \node[blue] at (9.5,\x) () {\bfseries \small 0};
        }
    \draw[red,line width=2pt] (0,0) rectangle (10,10);
    \draw[red,line width=2pt] (1,1) rectangle (9,9);
    \end{tikzpicture}
\end{document}

新的输出是：

Answer 2

anchor=center除了Ignasi 在评论中所说的之外，您可以设置text height并text depth：

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{matrix, backgrounds}

\newcommand{\0}{\scalebox{2}{$0$}}

\begin{document}

\begin{tikzpicture}[font=\scriptsize]
  \matrix (space) [matrix of math nodes, row sep=-\pgflinewidth, column sep=-\pgflinewidth, 
    nodes={draw, semithick, minimum height=10mm, minimum width=10mm, text height=7mm,
    text depth=3mm,
    inner sep=0pt,
    text=blue}]
{\0 & \0 & \0 & \0 & \0 & \0 & \0 & \0  & \0 & \0  \\ 
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\ 
 \0 &\  & \ & \ & \  &  \  & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 &\  & \ & \ & \  &  \ & \ & \  & \  & \0  \\
 \0 & \0 & \0 & \0 & \0  & \0  & \0 & \0  & \0  & \0  \\};
\draw[red, very thick] (space-1-1.north west) rectangle (space-10-10.south east);
\draw[red, very thick] (space-2-2.north west) rectangle (space-9-9.south east);
\end{tikzpicture}
\end{document}
