The way you mention columns in some of your responses leads me to believe this is a fixed width table, if not ignore this response. This uses DataExtract::FixedWidth

use DataExtract::FixedWidth;
use IO::File;
use feature ':5.10';
my $fh = IO::File->new( 'file.txt', 'r' );
my @tuples = <$fh>;

my $de = DataExtract::FixedWidth->new({ heuristic => \@tuples });

foreach my $tuple ( @tuples ) {
  state $row;
  my $arr = $de->parse( $tuple );
  given ( ++$row ) {
    when ( 1 ) { say $arr->[0] }
    when ( 2 ) { say $arr->[2] }
  }
}

or

my $de = DataExtract::FixedWidth->new({
 heuristic => \@tuples
 , column_names => [qw/foo bar baz/]
});

foreach my $tuple ( @tuples ) {
  state $row;
  my $hash = $de->parse_hash( $tuple );
  given ( ++$row ) {
    when ( 1 ) { say $hash->{foo} }
    when ( 2 ) { say $hash->{baz} }
  }
}
