Alex,

I'm supposed to guess what a table model is?

Hi Alex,
The datastore has a method: getClassMappings which returns an iterator of the in-memory hibernate mapping. You need to
study the returned objects in the debugger to see what you can do with it. But you can surely find the columns.

But... I am not sure if you want to use the database model for this. The great thing of EMF is that you have the model
at hand at runtime. So column count etc. can be retrieved from the in-memory ecore model.

The rowcount is something you have to compute yourselve using a hql/jpql query.

Alex,

I think you should do a bit of homework and then ask questions when
there's enough context for them to make sense. After all, EMF generated
editor already provides a table view, but my sense is you've not looked
at that.

Alex,

Nor will you find stuff about swing.

You'll have to look at how things like AdapterFactoryLabelProvider and
AdapterFactoryContentProvider interface with JFace's label and content
providers to figure out how to map those same ideas to swing.
