The only difference between a SimpleTable and an ExtendedTable is in the way you access items and fields in the concerning listeners. With a SimpleTable you must access items/fields by index while with an ExtendedTable you can access items/fields via their names.

Moreover in the SimpleTable constructor you pass a group and a schema that could be expanded MetaDataAdapter-side (for example you can use a group named "all", expand it on the metadata adapter listing all the available items and then subscribe them to the data adapter) while with the ExtendedTable you pass an array of items and an array of fields.


Please let me know if you want to expand more the topic.
