The PivotGrid component for Blazor is a lightweight and powerful data visualization widget.
It allows visualization of multi-dimensional and hierarchical data structures.
It also ships with a Pivot Table Designer widget. The Pivot Table Designer allows you to visually configure the pivot columns, rows, aggregated values and multiple different settings. You can also configure pivot rows and columns text alignment settings and various text formatting options on the pivot cells.
Before you start with the Pivot Grid widget, you should be familiar with pivot tables and understand when to use regular data grids to display table data, and when to switch to the pivot grid and pivot tables. The following article is a good entry-level introduction to pivot tables: Wikipedia: Pivot table
