Tenho lutado para descobrir o que há de errado com meu código. Atualmente tenho uma matriz com algumas cores e na margem gostaria de setas. No momento estou com isso

O primeiro número atualmente sangra na margem. Além disso, a segunda figura é quase uma réplica exata da primeira, mas quando quero adicionar setas verticais, obtenho um erro "Missing = inseriu for \ifnum." e "Número faltante, tratado como zero." Além disso, a última coluna é mesclada com a margem. Há algo que possa ser feito para corrigir isso?

Então, de fato, há um problema com o Overleaf em que o nicematrixpacote não é atualizado para a versão mais recente. Carregar o arquivo nicematrix.stypara meu projeto Overleaf corrigiu o problema. O arquivo pode ser encontrado no servidor SVN do TeXLive:www.tug.org/svn/texlive/trunk/Master/texmf-dist/tex/latex/nicematrix/nicematrix.sty
