Currently, there is a following signature of function "rowRender" passed to React Grid:

rowRender?: (row: React.ReactElement<HTMLTableRowElement>, props: GridRowProps) => React.ReactNode;

I managed to access something which I assume represents this index somehow by using "row._owner.index" although I'm not completely sure if that is always identical to the index of the row being rendered.

It would be very helpful if an index of a rendered row could be accessed as follows:

rowRender?: (row: React.ReactElement<HTMLTableRowElement>, props: GridRowProps, index: number) => React.ReactNode;
