we create a Custom List in SharePoint site, we need to map the list to View. By default when we create List, it will be mapped to "All Items" standard view. But we can change the view for the list.
below are the available view types
Standard View - View data on a Web page. You can choose from a list of display styles.
Calendar View - View data as a daily, weekly, or monthly calendar.
Datasheet View - View data in an editable spreadsheet format that is convenient for bulk editing and quick customization.
Gantt View - View list items in a Gantt chart to see a graphical representation of how a team's tasks relate over time.
Custom View in SharePoint Designer - Start SharePoint Designer to create a new view for this list with capabilities such as conditional formatting.
