Hi Boris,

Thanks for the provided information and for the feature request.

This specific scenario with both functionalities enabled is still not part of our immediate plans.

The reason why virtual columns + sticky columns is not supported is because the virtualization mechanic and pattern assumes there would be ordered columns and we have no mechanism to ensure that sticky columns will remain in the viewport.

What I can suggest is to use locked columns rather than sticky. The locked columns are similar to the sticky ones and can be used to achieve the same effect.

I've created a short StackBlitz demo to demonstrate the said above:
