I have some problems understanding your question. It seems you have your data in an array, i.e. @{$array_ref}. Note you can use this dereferenced array reference anywhere you need an array

Now Data::Pivot seems to need an Array of Arrays (often called simply AoA) for @table. And you probably have the data just in a simple array. Is that what you are getting at? In that case the following code would work (provided that you stored the number of columns into $columns):

my @table=();
my $row=0;
while (@{$array_ref}) {
  for (1..$columns) {
    push @{$table[$row]}, shift @{$array_ref};
  }
  $row++;
}

Now you can call pivot. To get the data into a simple array again you can use this:

my @table_linear;
map { push @table_linear, @{$_} }, @table;

or, if you prefer loops:

my @table_linear;
foreach (@table) { 
  push @table_linear, @{$_} 
}

If that isn't the answer to your question, please provide examples
