I liked your WebDatatRocks web pivot table tool very much because of type of features it has.
Also, I need some customization in fields (default rows, columns and Value).
Can you please provide me details on how to customize Fields in Angular2+.
Thank you for your kind words!
First of all, you will need to generate the report containing your default rows, columns and values. Check out the tutorial explaining how to get such report: Configuring fields.
This report file can later be used when you embed the pivot table:
<wbr-pivot #pivot1 [toolbar]="true"
WebDataRocks will appear here
Hope it helps.
