I'm attempting to upgrade from Kendo React 10.x to 11.x but there is a ton of breaking changes to the Grid component.
We have a lot of custom Grid cells that use the function prop syntax. The syntax that allows a function to be passed to the cell prop.
In version 11.x this function syntax appears to be removed.
Is there any way to pass additional props to a custom cell component, or a way to pass a function to the cell prop anymore?

Version 11 still supports the same syntax, it just looks different. The new syntax is as below, for example ...
cells={{
data: {(p)=> <GridDeleteCell .../>}
headerCell: {(p)=> <GridDeleteHeaderCell .../>}
...
}}
