            GridViewRow row = gridView.Rows[rowIndex];

            GridViewRow previousRow = gridView.Rows[rowIndex + 1];

            for (int cellIndex = 0; cellIndex < row.Cells.Count; cellIndex++)

            {

                if (row.Cells[cellIndex].Text == previousRow.Cells[cellIndex].Text)

                {

                    row.Cells[cellIndex].RowSpan = previousRow.Cells[cellIndex].RowSpan < 2 ? 2 : previousRow.Cells[cellIndex].RowSpan + 1;
