# column
> Format `stdin` or a file into multiple columns.
> Columns are filled before rows; the default separator is a whitespace.
> More information: <https://manned.org/column>.
- Format the output of a command for a 30 characters wide display:
`printf "header1 header2\nbar foo\n" | column {{[-c|--output-width]}} {{30}}`
- Split columns automatically and auto-align them in a tabular format:
`printf "header1 header2\nbar foo\n" | column {{[-t|--table]}}`
- Specify the column delimiter character for the `--table` option (e.g. "," for CSV) (defaults to whitespace):
`printf "header1,header2\nbar,foo\n" | column {{[-t|--table]}} {{[-s|--separator]}} {{,}}`
- Fill rows before filling columns:
`printf "header1\nbar\nfoobar\n" | column {{[-c|{{[-c|--output-width]}}]}} {{30}} {{[-x|--fillrows]}}`
