Enable combining nested rows and expandedRowRender

[jmatsushita]

Currently adding expandedRowRender on a table removes the indendation.

It would be great to have both! (it would help to visually break between parent and children in a nested table).

Could you describe it more detail? What's your use case?

[jmatsushita]

The idea is to have nested rows that also expand. The use case is hierarchical data for instance:

country
 + region A
 - region B
   - city  A

where each nested row also has additional data (for instance an image or long description) that can be displayed with an expandedRow.

country
 + region A
 - region B
 description...
   - city  A
   description...
