column — columnate lists
column [-entx] [-c columns] [-s sep] [file …]

-s Specify a set of characters to be used to delimit columns for the
-t Determine the number of columns the input contains and create a
table. Columns are delimited with whitespace, by default, or

-e Do not ignore empty lines.
The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the
execution of column as described in environ(7).
The column utility exits 0 on success, and >0 if an error occurs.
