Question

我已经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：当我试图重新计算公式时，我得到了一个例外。

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：

// 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（“评估cell =”+ c.getCellFormula（）的公式）; evaluator.setDebugEvaluationOutputForNextEval（真）; evaluator.evaluate（C）;

Answer 1

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

Answer 2

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))");
