Qlik Sense like QlikView should be able to handle large datasets no problem.
The practicalities of displaying the table however you may find as a user of Sense being asked to select which columns from the table you want to display if it wont fit nicely on your device display. This is Qlik Sense responsive layout working to ensure the user gets a nice experience. All the data there but you may be asked which to display at a given time.
