代码如下:

	

	 /// <summary>

	    /// 合并GridView中某列相同信息的行（单元格）

	    /// </summary>

	    /// <param name="GridView1"></param>

	    /// <param name="cellNum"></param>

	    public static void GroupCol(GridView GridView1, int cols)

	    {

	        if (GridView1.Rows.Count < 1 || cols > GridView1.Rows[0].Cells.Count - 1)

	        {

	            return;

	        }

	        TableCell oldTc = GridView1.Rows[0].Cells[cols];

	        for (int i = 1; i < GridView1.Rows.Count; i++)

	        {

	            TableCell tc = GridView1.Rows[i].Cells[cols];

	            if (oldTc.Text == tc.Text)

	            {

	                tc.Visible = false;

	                if (oldTc.RowSpan == 0)

	                {

	                    oldTc.RowSpan = 1;

	                }

	                oldTc.RowSpan++;

	                oldTc.VerticalAlign = VerticalAlign.Middle;

	            }

	            else

	            {

	                oldTc = tc;

	            }

	        }

	    }
