farpoint合计列不参与排序实现方法

private void neuSpread1_AutoSortingColumn(object sender, FarPoint.Win.Spread.AutoSortingColumnEventArgs e)
        {
            //重写排序方法
            e.Cancel = true;
            FarPoint.Win.Spread.SortInfo[] sorter = new FarPoint.Win.Spread.SortInfo[1];
            sorter[0] = new FarPoint.Win.Spread.SortInfo(e.Column, e.Ascending, System.Collections.Comparer.Default);
            this.neuSpread1_Sheet1.SortRows(0, this.neuSpread1_Sheet1.Rows.Count - 1, sorter);
        }

打印时需设置否则合计行打印不出来：
       this.neuSpread1_Sheet1.PrintInfo.UseMax = false;
