Data grid performance

This section will discuss what to consider for optimizing the data grid performance when working with large datasets.

What's new

Jspreadsheet version 10 introduces significant improvements and optimizations that enhance the performance and user experience of the application. One of the significant advancements is eliminating duplicate information and using global CSS classes for styling. This approach streamlines the code, making it more efficient and easier to manage. The new version includes a better navigation system that leverages the viewport to load only the data visible to the user. This feature enhances the user experience by creating a seamless and speedy performance while minimizing the application's resource utilization.

Smart viewport

You can activate the smarter viewport by enabling pagination, table overflow, or full-screen properties. Overall, the improvements and optimizations in Jspreadsheet version 10 provide users with a more efficient and smoother experience.

tableOverflow: boolean

It defines the viewport width and height dimensions.

fullscreen: boolean

This property is handy for rendering as many cells as possible to fit the screen.

pagination: number

This property activates the pagination feature, which displays a fixed number of rows and creates a pagination bar..

Examples

A data grid with 5 million cells

The following example will create a table from an array with 100 columns x 50000 rows (five million cells)
