-|**Table**<br> Reference a data table | `mltable` | `TabularDataset` | You have a complex schema subject to frequent changes, or you need a subset of large tabular data.<br><br>AutoML with Tables. | In V1 APIs, the Azure Machine Learning back-end stored the data materialization blueprint. As a result, `TabularDataset` only worked if you had an Azure Machine Learning workspace. `mltable` stores the data materialization blueprint in *your* storage. This storage location means you can use it *disconnected to AzureML* - for example, locally and on-premises. In V2 APIs, it's easier to transition from local to remote jobs.
