> To be able to create a pandas DataFrame in {{to_pandas()}} that holds ExtensionArrays (e.g. towards ARROW-2428 to register a conversion), we first need to add to the {{table_to_blockmanager}} / {{ConvertTableToPandas}} conversion utilities the ability to create an pandas {{ExtensionBlock}} that can hold a pandas {{ExtensionArray}}.
