I have been using a dGrid for a long time and have set them to update on extent change to only list what's shown in the current map extent.
I don't see that I have that level of control using FeatureTable. There's interaction from the table to the map, like Zoom to Selection, but nothing that goes the other way, map or layer to control the table.
I'd also have a definition expression tool I've added to limit the features on the map that way, and the table isn't honoring that either.
Am I missing something, or is that functionality just not available in a FeatureTable? Too bad if it isn't since it means offering something that is faster (FeatureTable) at the expense of loss of functionality.
