带公式添加行慢的问题

收藏

每行有27个公式,当添加多行的时候贴别慢，5行以下速度还可以接受。是否有建议提供。添加行的代码如下：
                        let sheet = this.spread.getActiveSheet();
                        this.sheet = sheet;
                        if (this.sheet) {
                              var rows = this.sheet.getRowCount(GC.Spread.Sheets.SheetArea.viewport);
                                          //增加行数开始
                              if(this.addRowNum<=0 || this.addRowNum==null){ //addRowNum为录入需要添加行数
                              this.addRowNum=1
                              }

                              sheet.addRows(sheet.getRowCount(SheetArea.viewport), Number(this.addRowNum));
                              //增加行数结束

                              // this.addArrayFormula();

                              var startrow=rows+1;
                              for(var i=0;i<Number(this.addRowNum);i++){
                                 var stringFomular = '';

                                 if (startrow >= 1) {
                                    for (let index = 0; index < this.conlumnCount; index++) {//设置公式
                                             //列是动态生成，公式也是动态生成
                                             var range = new GC.Spread.Sheets.Range(startrow-1, index*3+17, 1,1);
                                             var value = GC.Spread.Sheets.CalcEngine.rangeToFormula(range, 0, 0, GC.Spread.Sheets.CalcEngine.RangeReferenceRelative.allRelative);

                                             stringFomular = '=ROUND('+value+'*N'+startrow+'*O'+startrow+',0)';
                                             this.sheet.setFormula(startrow-1, index*3+18, stringFomular);
                                          }
                                 }
                                 startrow=startrow+1
                              }
                              this.sheet.getRange(0,0,this.sheet.getRowCount(),this.sheet.getColumnCount()).locked(false);
                        }
