Expand icon and styling change

Hi

I have below questions and would like to know whether react-bootstrap-table supports it.

1. I need to change the expand icon (+) to a triangle image.
2. I would like to achieve a white and grey color for alternate rows.

Is it possible to achieve in react-bootstrap-table. If so please advise.
Note: i could not migrate it to react-bootstrap-table2 due to time constraints.

Thanks
Ganesh
