Hi - it must be an undef in your array, your
join should work as posted.
You might try something like (untested):
for (@array) {
if ($_) {
push @clean_array, $_
}
}

Thanks for the correction. It seemed

undef() is not a test. undef() undefines things.
shift @columns if not defined $column[0];
The simplest solution is:
print j
As per my previous post, init your array with
@columns = ()
instead of
@columns = ""

It may be the case that there is the first value that
is not visible that is the value is a null string.
Otherwise it should work.
