效果如图 代码如下。

 private void RowSpan()    {        int n, m ,j;        for (int i = 0; i < GridView1.Rows.Count; i++)        {            n = 1;            for (j = i + 1; j < GridView1.Rows.Count; j++)            {                                if (GridView1.Rows[i].Cells[0].Text.Trim() == GridView1.Rows[j].Cells[0].Text.Trim())                {                    n += 1;                    GridView1.Rows[i].Cells[0].RowSpan = n;                    GridView1.Rows[j].Cells[0].Visible = false;                }                else                    break;                           }             i = j - 1;        }        for (int i = 0; i < GridView1.Rows.Count; i++)        {            m = 1;            for (j = i + 1; j < GridView1.Rows.Count; j++)            {                if (GridView1.Rows[i].Cells[1].Text.Trim() == GridView1.Rows[j].Cells[1].Text.Trim())                {                    m += 1;                    GridView1.Rows[i].Cells[1].RowSpan = m;                    GridView1.Rows[j].Cells[1].Visible = false;                }                else                    break;                            }            i = j - 1;        }    }
