[dat grid] Pivot advanced demo has an issue with object as column or value #18915
Description
Steps to reproduce
Steps:
- Open this link to the demo: https://mui.com/x/react-data-grid/pivoting/#advanced-demo
- Enable Pivot
- Select Counterparty Country as a column or value for pivot
Current behavior
The text of the column is [Object object] if use as a column.
The text of the cell is empty if used as a value. It chooses size for its aggregation.
Expected behavior
Displaying the value with the flag would be nice, if its too complicated just having the correct value would be enought.
For the value in the cell I figure that maybe size doesn't make sense, but in that case having a custom aggregation could be interesting to show. Either way, it should be just an empty cell.
Context
Most of the field in our grid is an object and I wanted to see how the advanced demo deal with those.
