Answer 1

You might want the column command, usually with --table / -t to produce basic tabular output:

From the man page:

 -t, --table 

Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the charac‐ters supplied using the --output-separator option. Table output is useful for pretty-printing.

column -t [file]

# or from stdin
cat file | column -t

# For a quick demonstration, format the output of mount
mount | column -t

column has a lot of other complex options. man column for details.
