coluna --table-noextreme

  • 772

Como funciona a --table-noextremeopção de columntrabalho?

   -E, --table-noextreme columns
      Specify columns where is possible to ignore unusually long 
      (longer than average) cells when calculate column width. 
      The option has impact to the width calculation and table
      formatting, but the printed text is not affected.


$ cat table.md
Lorem ipsum | Lorem ipsum dolor sit amet | Lorem ipsum dolor sit amet | Lorem ipsum dolor sit amet
Lorem | Lorem ipsum | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut | Lorem ipsum dolor
Lorem | Lorem ipsum dolor | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do | Lorem
$ column -t -s '|' -o '|' < table.md
Lorem ipsum | Lorem ipsum dolor sit amet | Lorem ipsum dolor sit amet                                                                   | Lorem ipsum dolor sit amet
Lorem       | Lorem ipsum                | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut | Lorem ipsum dolor
Lorem       | Lorem ipsum dolor          | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do                              | Lorem
$ column -t -s '|' -o '|' --table-noextreme 3 < table.md
Lorem ipsum | Lorem ipsum dolor sit amet | Lorem ipsum dolor sit amet                                                                   | Lorem ipsum dolor sit amet
Lorem       | Lorem ipsum                | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut | Lorem ipsum dolor
Lorem       | Lorem ipsum dolor          | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do                              | Lorem

Como posso obtê-lo para formatar a tabela como

Lorem ipsum | Lorem ipsum dolor sit amet | Lorem ipsum dolor sit amet | Lorem ipsum dolor sit amet
Lorem       | Lorem ipsum                | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut | Lorem ipsum dolor
Lorem       | Lorem ipsum dolor          | Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do | Lorem

    Seus dados de amostra não estão acionando o efeito de -E, provavelmente porque nenhum valor na terceira coluna pode ser determinado como "extraordinariamente longo".

    Usando este texto de exemplo modificado:

    Lorem ipsum | Lorem ipsum dolor | Lorem | Lorem ipsum dolor sit
Lorem ipsum dolor | Lorem | Lorem ipsum dolor sit amet, consectetur | Lorem
Lorem | Lorem ipsum | Lorem | Lorem ipsum dolor sit

    e uma largura de terminal de 80 colunas, recebo:

    $ column -t -s \| -o \| file
Lorem ipsum       | Lorem ipsum dolor | Lorem                                   | Lorem ipsum dolor sit
Lorem ipsum dolor | Lorem             | Lorem ipsum dolor sit amet, consectetur | Lorem
Lorem             | Lorem ipsum       | Lorem

    (com linhas se espalhando por várias linhas) e

    $ column -t -E 3 -s \| -o \| file
Lorem ipsum       | Lorem ipsum dolor | Lorem            | Lorem ipsum dolor sit
Lorem ipsum dolor | Lorem             | Lorem ipsum dolor sit amet, consectetur 
                  |                   |                  | Lorem
Lorem             | Lorem ipsum       | Lorem            | Lorem ipsum dolor sit

    No entanto, dada a saída esperada, a opção -l( --table-columns-limit) parece ser o que você está procurando:

    $ column -t -l 3 -s \| -o \| file
Lorem ipsum       | Lorem ipsum dolor | Lorem | Lorem ipsum dolor sit
Lorem ipsum dolor | Lorem             | Lorem ipsum dolor sit amet, consectetur | Lorem
Lorem             | Lorem ipsum       | Lorem | Lorem ipsum dolor sit
