Hi Sun,

I appreciate your interest in our RadGridView component for WinForms.

RadGridView doesn't support cells merging out of the box. You could achieve a similar look by using a custom code. A possible solution is demonstrated in the RadGridView Merge Cells KB article in our documentation. You can check the approach in the article and extend it per your requirements. 

In addition, there is a feature request logged in our Feedback Portal to implement such functionality. You can cast your vote to increase its priority. Don't forget to follow the feedback item so that you can be notified of its status change.
