(Ruby) DynamoDB - DeleteTable

The DeleteTable operation deletes a table and all of its items. After a DeleteTable request, the specified table is in the DELETING state until DynamoDB completes the deletion.

For more information, see https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_DeleteTable.html
