Formate a célula tabular do arquivo csv automaticamente

Question

Tentei adaptar exemplos de5.4 Tabelas com Formatação Numéricado csvsimplepacote, mas sem sucesso.

Cada linha do meu csvarquivo possui 20 campos,todos elestem formato como x.xxxxxx. Aqui está a primeira linha:

0.500000,0.614231,0.567667,0.580000,0.787222,0.510333,0.797333,0.732000,0.851228,0.804333,0.764000,0.730667,0.879667,0.778667,0.858333,0.726333,0.884000,0.772667,0.959545,0.919667

Eu gostaria de criar uma tabela para imprimir os dados, mastruncado, quero dizer, imprima apenas 3 casas decimais como x.xxx.

Eu sei que \csvloop{}tem a chave tabular={}para especificar o formato (como tabular={lSS[table-format=2.2e1]}no exemplo citado acima).

1. Como meu tabular deveria ter 20 colunas, é possívelformatar tudo automaticamente?

2. Qual deve ser o formato? S[table-format=1.3]?
