Good time! I have puzzled myself with rather easy problem: there is a list of hosts, each host has several configurations, and each configuration runs several tests. The resulting structure reminds the following: 
my %results;
$results{$host}{$config}{$test} = 'OK'; # or 'FAILED'

I would like to format them into a table 
---------------------------------
hosts | configs | tests | results
---------------------------------
host1 | conf1   | test1 | res1
      |         |----------------
      |         | test2 | res2
      |--------------------------
      | conf2   | test3 | res3
...
---------------------------------
host2 |
...

I could not figure out 'format' for such a table (all my attempts with multilines etc. brought nothing) and wonder if it's worth to look into CPAN for related functionality instead. Thanks for any ideas
