As already stated, your question is somewhat vague and doesn't give us a lot to work on.
We're happy to help you out with things you're stuck on (e.g. some aspect of Perl you're having difficulty understanding)
but this is not a code writing service.
Another good resource to help you improve your posts is "How do I post a question effectively?".
"... without changing the row format like padding and spacing."
Have a look at the printf
and sprintf functions.
These may help with this aspect of your problem.
Here's a quick example:
$ perl -e '
my $fmt = "%7s %7s %7s\n";
my $x = "JO EMS Math";
my $y = "Jon EMS Physics";
printf $fmt, split " ", $_ for $x, $y;
JO EMS Math
Jon EMS Physics
