Viewport

The viewport is a crucial feature in the JSS JavaScript grid, referring to the visible section of the table displayed on the user's screen. When enabled, the viewport option enhances JSS's performance, rendering only visible cells and boosting performance when dealing with massive data sets. There are two configurations available for enabling the viewport:

Fullscreen : This configuration sets the table dimensions to utilize the available screen area.
TableOverflow : This configuration enables the viewport along with the properties tableWidth and tableHeight, allowing developers to customize the viewport's width and height, respectively.
Pagination : This configuration defines the number of rows visible to the user and creates page navigation.

Developers can define these properties at the worksheet level, allowing them to set different viewport sizes for each worksheet. This capability enables developers to optimize data display for various devices or use cases. Falar sobre a definicao do viewport via style.
