Hi Aditi,
Use the TableModel.CoveredRanges property of the grid to set the covered ranges in a grid. Please try the attached sample and let me know if you are looking something different.
[C#]
this.gridGroupingControl1.TableModel.CoveredRanges.Add(GridRangeInfo.Cells(2,3,3,3));
this.gridGroupingControl1.TableDescriptor.Columns["FirstName"].HeaderText = "Name";
