我已经解决了这里发布的许多问题，也参考了 POI 文档，但我无法解决这个问题。

问题：尝试重新计算公式时出现异常。

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：

我做了以下尝试重新计算公式：

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

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

  3. for (Row r : sheet) { for (Cell c: r) { if (c.getCellType() == Cell.CELL_TYPE_FORMULA) { System.out.println("单元格计算公式 = " + c.getCellFormula()) ; evaluator.setDebugEvaluationOutputForNextEval(true); evaluator.evaluate(c);

启用 poi 日志后，我发现所在的单元格

=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"))

是依赖，也是excel公式。

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

这个公式有一个额外的逗号 (,)，它在解析公式时会导致 MissingArgument，而在评估这个 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参考的公式。

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))");
