FPSpread怎么根据目标行复制新行，并且新行的样式和目标行要相同

FPSpread怎么根据目标行复制新行，并且新行的样式和目标行要相同。

目前我是这样写的但是没有效果：
var currentSheets = spread.Sheets[0];
FarPoint.Web.Spread.Model.DefaultSheetSpanModel model1 = (FarPoint.Web.Spread.Model.DefaultSheetSpanModel)currentSheets.SpanModel;
model1.Copy(currentRowIndex - 1, 0, currentRowIndex, currentSheets.ColumnCount - 1, 1, currentSheets.ColumnCount);

您好，复制样式的代码如下，如果下面的代码对您不起作用，请提供个可以重现问题的页面，我们测试下，

1. private void Page_Load(object sender,System.EventArgs e)
   
2. {
   
3. if(this.IsPostBack)return;
   
4. 
   
5. FarPoint.Web.Spread.Model.DefaultSheetStyleModel model=(FarPoint.Web.Spread.Model.DefaultSheetStyleModel)FpSpread1.Sheets[0].StyleModel;
   
6. FarPoint.Web.Spread.StyleInfo style=new FarPoint.Web.Spread.StyleInfo();
   
7. style.BackColor=Color.Yellow;
   
8. model.SetDirectInfo(0,0,style);
   
9. }
   
10. 
    
11. private void Button1_Click(object sender,System.EventArgs e)
    
12. {
    
13. FarPoint.Web.Spread.Model.DefaultSheetStyleModel model=(FarPoint.Web.Spread.Model.DefaultSheetStyleModel)FpSpread1.Sheets[0].StyleModel;
    
14. model.Copy(0,0,2,0,1,1);
    
15. }
