    /// </summary> 
    /// <param name="GridView1">GridView</param> 
    /// <param name="cellNum">第几列</param> 
    public static void GroupRows(GridView GridView1, int [] cellNum)//已经改动过了现在是对指定多列后把相同信息合并
    {
        //int []arr = new int[cellNum.Length];
        //arr = cellNum;
        for (int num = 0; num < cellNum.Length; num++)
        {
            int i = 0, rowSpanNum = 1;
            while (i < GridView1.Rows.Count - 1)
            {
                GridViewRow gvr = GridView1.Rows[i];
                for (++i; i < GridView1.Rows.Count; i++)
                {
                    GridViewRow gvrNext = GridView1.Rows[i];
                    if (gvr.Cells[cellNum[num]].Text == gvrNext.Cells[cellNum[num]].Text)
                    {

                    else
