Apache POI org.apache.poi.ss.formula.FormulaParseException

Question

我正在使用 Apache POI，在评估公式单元格时遇到问题。

这是我的代码：

XSSFCell cellvalue = sheet.getRow(6).getCell(2);
if (cellvalue.getCellType() == cellvalue.CELL_TYPE_FORMULA) {
   evaluator.evaluateFormulaCell(cellvalue);
}

公式：

=C6/Num_Input and Num_Input = F36

问题：

org.apache.poi.ss.formula.FormulaParseException:
Cell reference expected after sheet name at index 18.

Answer 1

首先，离开 POI 并检查 Excel 本身是否公式运行正常。 POI端没有问题。我编写了这个示例代码并且运行良好。

        XSSFWorkbook workbook = new XSSFWorkbook();
        XSSFSheet sheet = workbook.createSheet();
        XSSFFormulaEvaluator evaluator = new XSSFFormulaEvaluator(workbook);
        XSSFCell cellvalue = sheet.createRow(0).createCell(0);
        sheet.getRow(0).createCell(1).setCellValue(2);
        sheet.getRow(0).createCell(2).setCellValue(5);
        cellvalue.setCellFormula("B1+C1");
        if (cellvalue.getCellType() == XSSFCell.CELL_TYPE_FORMULA) {
           evaluator.evaluateFormulaCell(cellvalue);
        }
        System.out.println(cellvalue.getNumericCellValue());

它的计算结果应该是 2 + 5 = 7。
