What shell are you using? What operating system are you using?
Does your shell provide a way to get the number of characters in the value of a variable?
If you have the number of characters in the value of a variable and the number characters in the field in which that value is to be centered, can you determine how many spaces and/or tabs need to be displayed before that value to center it in the first column?
If you have the number of characters in the value of the variable to be displayed in the 1st column and the number of characters in the value to be displayed in the 2nd column and the width of the 2nd column heading and the number of spaces between the 1st and 2nd column headings, can you figure out how many spaces and/or tabs need to be displayed between the two values to make the 2nd value appear in the center of the 2nd column?
Is the printf utility one of the utilities you're allowed to use for this assignment? If so, do you know how to specify the width of a string to be printed as a decimal value in the printf format string operand?
PS Please use CODE tags when showing us input and output as well as for shell code that you provide.

debconf-mergetemplate
DEBCONF-MERGETEMPLATE(1) Debconf DEBCONF-MERGETEMPLATE(1)
NAME
debconf-mergetemplate - merge together multiple debconf template files
SYNOPSIS
debconf-mergetemplate [options] [templates.ll ...] templates
DESCRIPTION
Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program.
This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified
files will be read in, merged, and output to standard output.
This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus
several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the
english versions of the fields they translated, for their reference.
So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the
translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the
main file (which might be more up-to-date).
This program handles that case properly, just list each of the translated templates files, and then your main templates file last.
OPTIONS
--outdated
Merge in even outdated translations. The default is to drop them with a warning message.
--drop-old-templates
If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire
template.
