Hi Hoàng,
Currently, we don’t have grouping/ungrouping support in
spreadsheet. However, we have considered this as a feature, and it
will be available in any of our upcoming releases. You can track the
status of this feature using below link from our feedback portal,
Feedback Portal Link: https://www.syncfusion.com/feedback/22846/grouping-support-in-spreadsheet
We usually have an interval of at
least three months between the releases. At the planning stage for every
release cycle, we review all open features once again and finalize features for
implementation based on specific parameters, including product vision,
technological feasibility, and customer interest. The feedback will be moved to
scheduled status with an estimated delivery period whenever we have more
information to provide regarding the development of this improvement. We
appreciate your patience until then.
