1.首先改变gridcontrol的MianView为BandedGridView

#region  创建合并表头  创建列
                BandedGridView view = this.bandedGridView1;
                view.BeginUpdate(); //开始视图的编辑，防止触发其他事件
                view.BeginDataUpdate(); //开始数据的编辑
    
                view.Bands.Clear();
                view.Columns.Clear();
    
    
                //创建表头
                GridBand bandOrderBillNo = view.Bands.AddBand("单号");
                GridBand bandDepName = view.Bands.AddBand("班组");
                GridBand bandStyleNo = view.Bands.AddBand("款号");
                GridBand bandStandardTime = view.Bands.AddBand("标准工时");
                GridBand bandBeginTime = view.Bands.AddBand("上线时间");
                GridBand bandEndTime = view.Bands.AddBand("下线时间");
                GridBand bandPlanQty = view.Bands.AddBand("订单计划数");
                GridBand bandSumQty = view.Bands.AddBand("累计生产数");
                GridBand bandSumBadQty = view.Bands.AddBand("不良总数");
                bandOrderBillNo.Visible = false;
                bandDepName.MinWidth = 175;
                bandStyleNo.MinWidth = 225;
                bandStandardTime.MinWidth = 125;
                bandBeginTime.MinWidth = 150;
                bandEndTime.MinWidth = 150;
                bandPlanQty.MinWidth = 100;
                bandSumQty.MinWidth = 100;
                bandSumBadQty.MinWidth = 100;
                // GridBand bandSumBadsdQty = view.Bands.Add(new GridBand() {Caption="hhh",Visible=true });
    
                //给表头绑定数据字段
                //方法1
                bandOrderBillNo.Columns.Add(new BandedGridColumn() { FieldName = "OrderBillNo", Visible = false });
                bandDepName.Columns.Add(new BandedGridColumn() { FieldName = "DepName", Visible = true });
                bandStyleNo.Columns.Add(new BandedGridColumn() { FieldName = "StyleNo", Visible = true });
                bandStandardTime.Columns.Add(new BandedGridColumn() { FieldName = "StandardTime", Visible = true });
                bandBeginTime.Columns.Add(new BandedGridColumn() { FieldName = "BeginTime", Visible = true });
                bandEndTime.Columns.Add(new BandedGridColumn() { FieldName = "EndTime", Visible = true });
                bandPlanQty.Columns.Add(new BandedGridColumn() { FieldName = "PlanQty", Visible = true });
                bandSumQty.Columns.Add(new BandedGridColumn() { FieldName = "SumQty", Visible = true });
                bandSumBadQty.Columns.Add(new BandedGridColumn() { FieldName = "SumBadQty", Visible = true });
    
                var dTime = Convert.ToDateTime(beginTime);
                while (dTime <= Convert.ToDateTime(endTime))
                {
                    string nextDay = dTime.ToString("yyyyMMdd");
    
                    GridBand BandTime = view.Bands.AddBand(dTime.ToString("MM月dd日"));
    
                    BandTime.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
                    
                    //给指定的表头添加下面列
                    GridBand bandP = BandTime.Children.AddBand("计划");
                    GridBand bandA = BandTime.Children.AddBand("实际");
                    GridBand bandW = BandTime.Children.AddBand("完成率%");
                    GridBand bandB = BandTime.Children.AddBand("不良");
                    //给列绑定值
                    //方法1
                    bandP.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "P", Visible = true  });
                    bandA.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "A", Visible = true });
                    bandW.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "W", Visible = true });
                    bandB.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "B", Visible = true });
    
                    //方法2   OwnerBand,该列的拥有者（上一级）
                    //view.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "P", OwnerBand = bandP, Visible = true });
                    //view.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "A", OwnerBand = bandA, Visible = true });
                    //view.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "W", OwnerBand = bandW, Visible = true });
                    //view.Columns.Add(new BandedGridColumn() { FieldName = nextDay + "B", OwnerBand = bandB, Visible = true });
    
                    dTime = dTime.AddDays(1);
                }
                #endregion
    
                view.EndDataUpdate();//结束数据的编辑
                view.EndUpdate();   //结束视图的编辑
