def delete_entity(self, partition_key, row_key,<EOL>if_match='<STR_LIT:*>'):
request = _delete_entity(partition_key, row_key, if_match)<EOL>self._add_to_batch(partition_key, row_key, request)<EOL>
Adds a delete entity operation to the batch. See 
:func:`~azure.storage.table.tableservice.TableService.delete_entity` for more 
information on deletes.

The operation will not be executed until the batch is committed.

:param str partition_key:
    The PartitionKey of the entity.
:param str row_key:
    The RowKey of the entity.
:param str if_match:
    The client may specify the ETag for the entity on the 
    request in order to compare to the ETag maintained by the service 
    for the purpose of optimistic concurrency. The delete operation 
    will be performed only if the ETag sent by the client matches the 
    value maintained by the server, indicating that the entity has 
    not been modified since it was retrieved by the client. To force 
    an unconditional delete, set If-Match to the wildcard character (*).
