Expanding shell variables directly within a printf format string is a bad idea; it sh it can lead to unpredictable behavior (in C, it's a serious security hole) if something in those variables resembles a format specifier (%s, %d, %%, etc).
No offense, but I cannot be bothered to analyze your output and reverse engineer the values of your variables.
You should show us the code you are using in its entirety or at the very least print out the value of each variable for each line of output. Then the actual output for those values followed by the desired output.
Regardless of any of the above, your format will be wrecked if any string exceeds its alloted width unless the format specifier truncates it by specifying a precision. In case it's illuminating compare this ...
against this ...
If your output format must accommodate fields of unpredictable widths, and if you are unwilling to truncate them, then you must resort to inspecting all of the output, storing it in the meantime, and then dynamically generating a format string which can accommodate the widest value in each column.
This is for an Oracle journal import. I was using a pl/sql package and oracle API's. Oracle added invoker rights to their API's and now my package won't run. I didn't want to use their API's anyway. The only reason i was using pl/sql and the API's (just a package) was to utilize a cursor. How... (2 Replies)

column
COLUMN(1) BSD General Commands Manual COLUMN(1)NAME
column -- columnate lists
SYNOPSIS
column [-ntx] [-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.
-n By default, the column command will merge multiple adjacent delimiters into a single delimiter when using the -t option; this option
disables that behavior. This option is a Debian GNU/Linux extension.
ENVIRONMENT
The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7).
EXIT STATUS
The column utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ;
printf "HH:MM/YEAR NAME
" ;
ls -l | sed 1d) | column -t
SEE ALSO colrm(1), ls(1), paste(1), sort(1)HISTORY
The column command appeared in 4.3BSD-Reno.
BUGS
Input lines are limited to LINE_MAX (2048) bytes in length.
