    Hi Rajeev,

    What you are asking for does seem a little bit funky. Please be aware that this type of formatting works only on even-width screens. Tabs are also very importable, since different applications may render them in different ways.

    That being said, I can see two routes:

    1. Perl does provide formats
    perldoc -f format
    that can help align your output for even-width renderings.

    2. Try the printf and sprintf functions. Once you get accustomed to the syntax [inherited from C] of their format strings and escapes, you may find them very handy. You can specify the width, alignment, and space or zero-padding, of you output
    very succinctly using these functions:
    perldoc -f printf
    perldoc -f sprintf

    Overall, I might recommend using or generating HTML for a job like this. This is the sort of work that markup was built for.
