FILE: sample_create_delete_table_async.py
DESCRIPTION:
These samples demonstrate creating and deleting individual tables from the
TableServiceClient and TableClient
USAGE:
python sample_create_client_async.py
Set the environment variables with your own values before running the sample:
1) TABLES_STORAGE_ENDPOINT_SUFFIX - the Table service account URL suffix
2) TABLES_STORAGE_ACCOUNT_NAME - the name of the storage account
3) TABLES_PRIMARY_STORAGE_ACCOUNT_KEY - the storage account access key
