You might want to consider a simpler rearrangement:
Have a hash where the keys are what is currently in 'columns' and the values are what is currently in 'table'.
$rowHash->{id} = 168; for example.
Depending on how you want to use them, you could make an array of such hashes, or a hash of those hashes (with the keys being some unique combination of data, such as the ID).

By having just a hash of hashes, you can manipulate the "table rows" much easier.

$rowHash = {id=>168, name=>'Jack'}; # create row
$tableHash->{$rowHash->{id}} = $rowHash; # add row to table
delete $tableHash->{$rowHash->{id}};  # delete row from table
$tableHash->{168}{name} = 'Jill'; #update single value
