Each table in Airtable can have any number of views. Views, as the name implies, allow you to "view" your records in different ways. For example, you may create a view that hides several fields and only shows task records that have been assigned to you. Whenever you hide or reorder fields, apply filters, or sort and reorder records, those changes will only apply to your current view. However, editing the record data or changing and deleting fields will apply to all views. Adding a new field will also make it appear in all views.
The name of the view that you are currently viewing is located in the top left-hand corner of the screen.
Clicking the name of the view will open the views menu. From here you can select or create a view.
