thanks for your reply. I'm a bit puzzled with the regex.

in thread Data::Table - empty values - avoid warnings
((defined($_->) && $_-> =~ m/^\d+$/) ? $_-> : 0)
Am I correct if I assume that here $_ is defined as 'one single digit or maybe a few digits (d+, no spaces and stuff like that in between the digits) and then if this is not the case it should be a 0 (zero)? Never used this ternary operator and just want to make sure that's what it is.
