So here you go:

use strict;
use warnings;

my @tablenums = ('1', '2', '3');
my (@johnData, @mikeData, @harryData);
my @any = ("any", "data", "goes", "here");

my %Tables = (
'1' => "john",
'2' => "mike",
'3' => "harry",
);
foreach (@tablenums){
eval "push \@${Tables{$_}}Data, (\"" . join ('","', @any, $_) . "\");"
+;
}

print "john`s data is @johnData!";
#prints "john`s data is any data goes here 1!"

I think you should read the documentation of eval() again.
