Como posso fazer uma matriz grande parecer boa?

Tenho que colocar matrizes grandes na minha tese e não consigo encontrar uma maneira de fazer isso de uma forma bonita. O problema é: essas matrizes são muito esparsas, mas preciso delas completas para fins de análise.

Até agora consegui representá-los assim (deixando espaços em branco onde o valor é 0): Minha matriz feia

Acontece que a matriz é 14x14, mas preciso que a primeira linha/coluna mostre o número 1->14.

Alguma ideia de como melhorá-lo mantendo a integridade?

EDITAR: Aqui está o MWE:

Veja como eu mudaria isso. A beleza de uma mesa pode ser subjetiva, mas acho que as linhas apenas adicionam ruído e tornam "mais difícil" ler a mesa confortavelmente. Prefiro usar apenas linhas horizontais (esparsas) ou cores de linhas alternativas, como neste caso.

Quaisquer pacotes ou comandos adicionados foram comentados no código como uma explicação rápida. Poste um comentário se você tiver dúvidas específicas.

Editar: adicionei o alinhamento adequado dos valores numéricos de acordo com o separador decimal.

Se você realmente deseja as linhas verticais, pode adicionar \arrayrulecolor{gray!30}logo abaixo \rowcolors{2}{gray!10}{white}. Substitua também o cabeçalho tabular por este: \begin{tabular}{.*{13}{.|}{.}}, desta forma, as regras verticais aparecem apenas nas células e não nas laterais da tabela.
