首先，大家好，谢谢-经过多年在StackOverflow上找到好的答案，我终于创建了一个帐户来问我的第一个问题：-）
当将NiceMatrix-Package与\ Block-Command一起使用时，会发生此问题。如果该块覆盖的矩阵指标超过10，则似乎存在问题。
首先是一个有效的示例：
\documentclass[12pt]{article}
\usepackage{amsmath}
\setcounter{MaxMatrixCols}{15}
\usepackage[latin1]{inputenc}
\usepackage{nicematrix}
\begin{document}
\begin{equation}
\begin{bNiceArray}{CCC|CCC|CCCCC}[first-row,first-col]
& a & b & c & d & e & f & g & h & i & j & k \\
a & \Block{3-3}{A} & & & \Block{3-3}{B} & & & \Block{3-3}{C} & & & & \\ % does compile
b & & & & & & & & & & & \\
c & & & & & & & & & & & \\
d & \Block{3-3}{D} & & & \Block{3-3}{E} & & & 0 & 0 & 0 & 0 & 0 \\
e & & & & & & & 0 & 0 & 0 & 0 & 0 \\
f & & & & & & & 1 & 0 & 0 & 0 & 0 \\
g & 0 & 0 & 0 & \Block{3-3}{F} & & & 0 & 1 & 0 & 0 & 0 \\
h & 0 & 0 & 0 & & & & 0 & 0 & 1 & 0 & 0 \\
i & 0 & 0 & 0 & & & & 0 & 0 & 0 & 1 & 0 \\
j & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 1
\end{bNiceArray}
\end{equation}
\end{document}
不起作用：
\documentclass[12pt]{article}
\usepackage{amsmath}
\setcounter{MaxMatrixCols}{15}
\usepackage[latin1]{inputenc}
\usepackage{nicematrix}
\begin{document}
\begin{equation}
\begin{bNiceArray}{CCC|CCC|CCCCC}[first-row,first-col]
& a & b & c & d & e & f & g & h & i & j & k \\
a & \Block{3-3}{A} & & & \Block{3-3}{B} & & & \Block{3-5}{C} & & & & \\ % does not compile
b & & & & & & & & & & & \\
c & & & & & & & & & & & \\
d & \Block{3-3}{D} & & & \Block{3-3}{E} & & & 0 & 0 & 0 & 0 & 0 \\
e & & & & & & & 0 & 0 & 0 & 0 & 0 \\
f & & & & & & & 1 & 0 & 0 & 0 & 0 \\
g & 0 & 0 & 0 & \Block{3-3}{F} & & & 0 & 1 & 0 & 0 & 0 \\
h & 0 & 0 & 0 & & & & 0 & 0 & 1 & 0 & 0 \\
i & 0 & 0 & 0 & & & & 0 & 0 & 0 & 1 & 0 \\
j & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 1
\end{bNiceArray}
\end{equation}
\end{document}
当然，矩阵C的大小应为3-5，而不是3-3，以覆盖矩阵内部的空白空间。但是替换后“ \ Block {3-3} {C}”与“ \ Block {3-5} {C}”（这是两个示例之间的唯一区别），我得到以下错误消息：
Package pgf Error: No shape named `nm-1-col-21' is known. \end{bNiceArray}
如果有解决方法或类似的方法，我会很高兴。
提前感谢！
