I was going through a snippet of code and I didn't understand the following notation (line 5 in the code below]. I am confused as how can a hash be represented as an array or is it a different form of hash of arrays or is array of hashes. The code is as follows: 

my @Data;
my @cols = qw(col1 col2 col3 col4);
while (<STDIN>) {
chomp;
my %table;
@table{@cols} = split /\t/; ## Explain
push @Data, \%table;
}
