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