your table assigned a datasource , datasource assigned to a Layer , layer assigned to a map , map assigned to MapView . MapView has a RenderManager,  and renders  Layers of a Map  to screen.   So if you want to display smith on screen you must create a datasource. 
If you don't want to connect mysql directly ( that s i understand)  gather your parameters that describes which features ll be shown , create features  in stratch datasource  , or object datasource using geotools and display it . 

If you want to display your features when you selected to a view ( Your Data Table) use WorkbenchSeletionListener . whenever your table selected by user 
new AddLayerCommand(yourlayer).run(..)
whenever deselected  new RemoveLayerCommand(yourlayer).run(...)

i hope this helps you.

uDig TableView works by:

1) Watching the workbench selection for the next "selected" Layer
2) Layer -> GeoResource
3) GeoResource.canResolve( SimpleFeatureStore.class ) = true; and then GeoResource.resolve( SimpleFeatureStore.class, progress) --> SimpleFeatureStore
4) SimpleFeatureStore.features( Query ) --> SimpleFeatureCollection

The SimpleFeatureCollection is what is displayed…

There should be examples of how to add your database to the uDig catalog.

The example for PostGIS as as follows:
Map<String,Serializable> params = new HashMap<String,Serializable>();
params.put("dbtype", "postgis");           // must be "postgis"
params.put("host", "www.refractions.net"); // the name or ip address of the machine running PostGIS
params.put("port", new Integer(5432));     // the port that PostGIS is running on (generally 5432)
params.put("database", "demo-bc");         // the name of the database to connect to.
params.put("user", "demo");                // the user to connect with
params.put("passwd", "demo");

IRepository local = CatalogPlugin.getDefault().getLocal();
IService service = local.acquire( params, new NullProgressMonitor() );
Or you may wish to try using the GeoTools classes directly? Notice this page also has the connection parameters to use with the uDig catalog above.
