@jerryjliu , I just updated the comments of the try_display method to make it less confusing. And I also updated the notebook, which includes the data frame output (tables) to make it easier to understand. And added a notebook block (see the last notebook) to do chat('run it') to make sure a query can be executed based on the context.
