import com.spire.xls.*; public class DataValidation { public static void main(String[] args) { //创建Workbook对象 Workbook workbook = new Workbook(); //获取第一个工作表 Worksheet sheet = workbook.getWorksheets().get(0); //在单元格B3中设置数字验证-仅允许输入1到100之间的数 sheet.getCellRange("B2").setText("请输入1-100之间的数："); CellRange rangeNumber = sheet.getCellRange("B3"); rangeNumber.getDataValidation().setCompareOperator(ValidationComparisonOperator.Between); rangeNumber.getDataValidation().setFormula1("1"); rangeNumber.getDataValidation().setFormula2("100"); rangeNumber.getDataValidation().setAllowType(CellDataType.Decimal); rangeNumber.getDataValidation().setErrorMessage("Please input correct number!"); rangeNumber.getDataValidation().setShowError(true); rangeNumber.getCellStyle().setKnownColor(ExcelColors.Color21); //在单元格B6中设置日期验证-仅允许输入1/1/1970到12/31/1970之间的日期 sheet.getCellRange("B5").setText("请输入1/1/1970-12/31/1970之间的日期："); CellRange rangeDate = sheet.getCellRange("B6"); rangeDate.getDataValidation().setAllowType(CellDataType.Date); rangeDate.getDataValidation().setCompareOperator(ValidationComparisonOperator.Between); rangeDate.getDataValidation().setFormula1("1/1/1970"); rangeDate.getDataValidation().setFormula2("12/31/1970"); rangeDate.getDataValidation().setErrorMessage("Please input correct date!"); rangeDate.getDataValidation().setShowError(true); rangeDate.getDataValidation().setAlertStyle(AlertStyleType.Warning); rangeDate.getCellStyle().setKnownColor(ExcelColors.Color16); //在单元格B9设置字符长度验证-仅允许输入5个字符以内的文本 sheet.getCellRange("B8").setText("请输入不超过5个字符的文本："); CellRange rangeTextLength = sheet.getCellRange("B9"); rangeTextLength.getDataValidation().setAllowType(CellDataType.TextLength); rangeTextLength.getDataValidation().setCompareOperator(ValidationComparisonOperator.LessOrEqual); rangeTextLength.getDataValidation().setFormula1("5"); rangeTextLength.getDataValidation().setErrorMessage("Enter a Valid String!"); rangeTextLength.getDataValidation().setShowError(true); rangeTextLength.getDataValidation().setAlertStyle(AlertStyleType.Stop); rangeTextLength.getCellStyle().setKnownColor(ExcelColors.Color14); //在单元格B12设置数字验证-仅允许输入大于等于18的整数 sheet.getCellRange("B11").setText("请输入大于等于18的整数："); CellRange rangeinteger = sheet.getCellRange("B12"); rangeinteger.getDataValidation().setAllowType(CellDataType.Integer); rangeinteger.getDataValidation().setCompareOperator(ValidationComparisonOperator.GreaterOrEqual); rangeinteger.getDataValidation().setFormula1("18"); rangeinteger.getDataValidation().setErrorMessage("Enter a Valid String!"); rangeinteger.getDataValidation().setShowError(true); rangeinteger.getDataValidation().setAlertStyle(AlertStyleType.Stop); rangeinteger.getCellStyle().setKnownColor(ExcelColors.LightGreen1); //第二列自适应宽度 sheet.autoFitColumn(2); //保存文档 workbook.saveToFile("DataValidation.xlsx", ExcelVersion.Version2016); } }
