      如果需要合并的列是模板列，就使用下面的方法。
 
      //ControlID:模板列控件的ID
 
     private void MergeGridTemplateCell(int iColumns,string ControlID)    {
         int row ; 
 
         int col ; 
         int count;
         row = 0;
         count = 0;
         for (col = 1; col < this.GridView1.Rows.Count; col++)
         {
             if (((Literal)GridView1.Rows[col - 1].Cells[iColumns].FindControl(ControlID)).Text == ((Literal)GridView1.Rows[col].Cells[iColumns].FindControl(ControlID)).Text)//"litDay"
             {
                 row = row + 1;
                 GridView1.Rows[col].Cells[iColumns].Visible = false;
                 if (col == GridView1.Rows.Count - 1)
                 {
                     row = row + 1;
                     GridView1.Rows[count].Cells[iColumns].RowSpan = row;
                     count = 0;
                 }
             }
             else
             {
                 GridView1.Rows[count].Cells[iColumns].RowSpan = row + 1;
                 row = 0;
                 count = col;
             }
         }
     }
