想要实现的效果如下：表格每一行都有一个曲线

TreeList与GridControl的设置方法类似。

1、先创建控件的数据源，我使用的是DataTable

        /// <summary>
        /// 生成一个DataTable
        /// </summary>
        /// <returns></returns>
        public static DataTable GetDataSource()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("ID", typeof(Int32))
            {
                AllowDBNull = false,
                AutoIncrement = true,
                AutoIncrementSeed = 1,
                AutoIncrementStep = 1
            });
            dt.Columns.Add(new DataColumn("Name", typeof(string)));
            dt.Columns.Add(new DataColumn("Year", typeof(int)));
            for (int i = 1; i <=12 ; i++)
            {
                dt.Columns.Add(new DataColumn($"{i}月", typeof(double)));
            }
            dt.Columns.Add(new DataColumn("RowSum", typeof(double)));
            dt.Columns.Add(new DataColumn("RowAvr", typeof(double)));

            int index = 1;
            List<string> names = new List<string> { "张三","李四","王五"}; 
            foreach (var name in names)
            {
                for (int year = 2021; year <= 2024; year++)
                {
                    var random = new Random(year);
                    double sum = 0;
                    double[] numbs = new double[12];
                    for (int i = 0; i < numbs.Length; i++)
                    {
                        numbs[i] = random.NextDouble() * 100;
                        sum += numbs[i];
                    }

                    var itemArr = new List<object>() { index++, name, year };
                    Array.ForEach(numbs, x => itemArr.Add(x));
                    itemArr.Add(sum); 
                    itemArr.Add(sum / 12 );
                    dt.Rows.Add(itemArr.ToArray());
                    
                }  
            } 
            return dt;
        }

2、创建Column（与平时使用方法相同）

这里要注意的是：

（1）要显示曲线的那列需要指定ColumnEdit使用的是SparklineEdit控件；

（2）曲线列的UnboundType的Object

3、创建曲线列RepositoryItemSparklineEdit的View对象，具体代码如下：

            //绑定数据源
            gridControl1.DataSource = Bll.BllMain.GetDataSource();

            //创建view对象
            var view = SparklineViewBase.CreateView(SparklineViewType.Line) ;
            if(view is LineSparklineView lineSparklineView)
            {
                //设置lineView上的每个点都有Marker
                lineSparklineView.ShowMarkers = true;
                //设置Marker的颜色
                lineSparklineView.MarkerColor = Color.Gold;
            }
            //设置view的颜色
            view.Color = Color.Blue; 
            
            //设置点高亮显示
            view.HighlightEndPoint = true;
            view.HighlightStartPoint = true;
            view.HighlightMaxPoint = true;
            view.HighlightMinPoint = true;
            
            //设置点的颜色
            view.MaxPointColor = Color.Red;
            view.MinPointColor = Color.Orange;
            view.StartPointColor = Color.DarkGreen;
            view.EndPointColor = Color.Purple;

            //把view对象绑定到单元格控件上
            repositoryItemSparklineEdit1.View = view;

4、RepositoryItemSparklineEdit列对应的数据是Object，我们需要通过代码指定这列具体单元格对应的的数据源

        private void gridView1_CustomUnboundColumnData(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e)
        {
            if (e.IsGetData)
            { 
                List<double> values = new List<double>();
                DataRowView row = (DataRowView)e.Row;
                for (int i = startIndex; i < startIndex+12; i++)
                {
                    values.Add((double)row.Row.ItemArray[i]);
                }
                e.Value = values;//指定单元格的数据源
            }
        }

通过以上代码及设置即可实现想要的效果
