Question

我需要检查用户是否在单元格A1：A10中输入了有效数字。在Excel中，我将选择单元格，然后创建自定义验证器并将公式设置为= isNumber（“$ A $ 1：$ A10”）尝试使用POI做这件事让我全都陷入困境：这是我尝试过的：

CellRangeAddressList addressList = new CellRangeAddressList(0, 10, 0, 0);
        XSSFDataValidationHelper dvHelper = new XSSFDataValidationHelper(sheet);
        DataValidationConstraint customConstraint = dvHelper.createCustomConstraint("isNumber(\"$A$0:$A$10\"");
        XSSFDataValidation validation = (XSSFDataValidation)dvHelper.createValidation(customConstraint, addressList);
        validation.setShowErrorBox(true);
        sheet.addValidationData(validation);

当我尝试在Excel中打开它时，我收到错误并且Excel禁用验证

提前谢谢 -anish

Answer 1

CellReference crStartCell = new CellReference(startRow, column, true, true); // 0-based row and column index
CellReference crEndCell = new CellReference(endRow, column, true, true);
XSSFDataValidationConstraint dvConstraint = (XSSFDataValidationConstraint) dvHelper.createCustomConstraint("ISNUMBER("+crStartCell.formatAsString()+":"+crEndCell.formatAsString() +")");

Answer 2

您可以将该Excel转换为csv，而不是使用SuperCSV执行验证。这将是长度，但更容易。

POI - 无法为一系列单元格创建自定义验证
