Think I know why you're confused what column to use: You don't have any columns, the file's just sitting there. Assuming the file's columns are still whitespace separated after all the tr-ing and awking you did, this will do:
I don't know what df's output looks like on your system, you may have more columns or less, but you get the idea.
I'm not to great with loops atm. I am wondering what
will do?

column
COLUMN(1) BSD General Commands Manual COLUMN(1)NAME
column -- columnate lists
SYNOPSIS
column [-tx] [-c columns] [-s sep] [file ...]
DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by
default, from the standard input. Empty lines are ignored.
The options are as follows:
-c Output is formatted for a display columns wide.
-s Specify a set of characters to be used to delimit columns for the -t option.
-t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with
the characters supplied using the -s option. Useful for pretty-printing displays.
-x Fill columns before filling rows.
column exits 0 on success, >0 if an error occurred.
ENVIRONMENT
COLUMNS The environment variable COLUMNS is used to determine the size of the screen if no other information is available.
EXAMPLES
(echo "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME";
ls -l | sed 1d) | column -t
