That stores a hash reference (to an anonymous hash) in $table. try:
print ref($table)
It initializes an empty hash that you can then add key/values to, for instance:
$table->{'newkey'} = 'newvalue';
But again read the perldocs listed at the top.

I believe, this passes an array reference to somefunction, and that references an
array with a single element $table.
So inside of somefunction you could then say
$_[0]->[0]
which would equal the value of $table.
Again the perldocs should clear things up a lot.
