java - Apache POI : Exception while calculating formulae

Question

我已经解决了这里发布的许多问题并引用了 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"))

异常(exception):

我做了以下尝试来重新计算公式:

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

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

3. for (Row r : sheet) {对于(单元格 c:r){ 如果(c.getCellType()== Cell.CELL_TYPE_FORMULA){ System.out.println("计算单元格的公式 = "+ c.getCellFormula()); evaluator.setDebugEvaluationOutputForNextEval(true); evaluator.evaluate(c);

Answer 1

启用 poi 日志后，我发现

=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 (,)，这导致在解析公式时出现 MissingArgument，并且在计算这个 Missing Argument 时导致 IllegalArgumentException。

POI 日志显示:
