Kendo Grid - Aggregation total at groupHeader

Hello,

 I can suggest checking the following article showcasing how to customize the groupHeader in order to show extra information in it:

https://www.telerik.com/kendo-react-ui/knowledge-base/render-a-custom-content-inside-the-grid-group-header/



As this is custom content, the developer has to apply the required styling and alignment of the content. https://stackblitz.com/edit/react-jakjt8?file=app/main.jsx

Also I modified that demo to showcase, how to use a colSpan to position the extra content over a column:

I hope this is helpful. 

Regards,
