Apache POI：计算公式时出现exception
我在这里发布了很多问题并提到了POI文档，但我无法解决这个问题。
问题：当试图重新计算公式时，我得到一个例外。
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：

我做了以下尝试重新计算公式：
-
// ExcelFile.workbook.getCreationHelper（）。createFormulaEvaluator（）。evaluateAll（）;
-
// HSSFFormulaEvaluator.evaluateAllFormulaCells（ExcelFile.workbook）;
-
for（Row r：sheet）{for（Cell c：r）{if（c.getCellType（）== Cell.CELL_TYPE_FORMULA）{System.out.println（“cell of formula =”+ c.getCellFormula（）） ; evaluator.setDebugEvaluationOutputForNextEval（真）; evaluator.evaluate（C）;
启用poi日志后，我发现其中的单元格
=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"))
依赖，也是excel公式。
=CONCATENATE(" {",HZ5," - ",IA5,"}, ","{",IB5,,"}")
这个公式有一个额外的逗号（，），它在解析公式时导致了一个MissingArgument，并且在评估这个Missing Argument时会导致IllegalArgumentException。
POI日志显示：
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
POI现在可以评估将范围运算符应用于区域引用的公式。
但是，POI仍然无法解析这些公式。 例如，这些调用将失败：
cell.setCellFormula("AVERAGE(J6:OFFSET(I6,0,DAY(TODAY())-1))"); cell.setCellFormula("SUM((C1:D2):(D2:E3))");
