Apache POI：計算公式時出現異常

Question

我已經通過這裏發佈了許多問題並提及了POI文檔，但我無法解決此問題。

問題：當試圖重新計算公式時，我收到一個異常。

公式：

=CONCATENATE("#DFLT=",COUNTIF(C5:C390,"=DEFAULTERS"),"; #NP=",COUNTIF(C5:C390,"=NOT PAID"),"; #PCsh=",COUNTIF(C5:C390,"=Paid Cash"),"; #PChk=",COUNTIF(C5:C390,"=Paid Cheque"),"; #PNeft=",COUNTIF(C5:C390,"=Paid Neft")) 

例外：

我提出以下嘗試重新計算公式：

1. // ExcelFile.workbook.getCreationHelper（）createFormulaEvaluator （）.evaluateAll（）;

2. // HSSFFormulaEvaluator.evaluateAllFormulaCells（ExcelFile.workbook）;

3. 爲（行r：片）{ （電池C：R）{ 如果（c.getCellType（）== Cell.CELL_TYPE_FORMULA）{ 的System.out.println（「評估公式用於細胞= 「+ c.getCellFormula（））; evaluateator.setDebugEvaluationOutputForNextEval（true）; evaluateator.evaluate（c）;

Answer 1

使POI日誌後我發現電池上

=CONCATENATE("#DFLT=",COUNTIF(C5:C390,"=DEFAULTERS"),"; #NP=",COUNTIF(C5:C390,"=NOT PAID"),"; #PCsh=",COUNTIF(C5:C390,"=Paid Cash"),"; #PChk=",COUNTIF(C5:C390,"=Paid Cheque"),"; #PNeft=",COUNTIF(C5:C390,"=Paid Neft")) 

依賴，是也擅長公式。

=CONCATENATE(" {",HZ5," - ",IA5,"}, ","{",IB5,,"}") 

這個公式有一個額外的逗號（，），這是引起MissingArgument在解析公式，同時評估IllegalArgumentException異常這個缺少的參數結果。

POI日誌顯示：

10-30 16:56:18.377: I/System.out(26511): [POI.FormulaEval]I  * ptg 7: org.apache.poi.ss.formula.ptg.MissingArgPtg [ ] 
10-30 16:56:18.377: I/System.out(26511): [POI.FormulaEval]I   = org.apache.poi.ss.formula.eval.MissingArgEval@42be7f58 

Answer 2

POI現在可以評估其適用的範圍內操作員區裁判公式。

但是，POI仍然不能解析這些公式。例如，這些調用將失敗：

cell.setCellFormula("AVERAGE(J6:OFFSET(I6,0,DAY(TODAY())-1))"); 
cell.setCellFormula("SUM((C1:D2):(D2:E3))");
