    {
        public static void Run()
        {
            // Create a workbook
            Workbook workbook = new Workbook();
            Worksheet worksheet = workbook.Worksheets[0];

            // Add sample data for validation
            worksheet.Cells["A1"].PutValue(10);
            worksheet.Cells["A2"].PutValue(20);
            worksheet.Cells["A3"].PutValue(30);
            worksheet.Cells["A4"].PutValue(40);

            // Create a validation range
            CellArea area = CellArea.CreateCellArea("B1", "B5");
            int validationIndex = worksheet.Validations.Add(area);
            Validation validation = worksheet.Validations[validationIndex];

            // Set validation properties with Operator demonstration
            validation.Type = ValidationType.WholeNumber;
            validation.Operator = OperatorType.Between;
            validation.Formula1 = "10";
            validation.Formula2 = "30";
            validation.ShowError = true;
            validation.ErrorMessage = "Value must be between 10 and 30";

            // Save the workbook
            workbook.Save("ValidationOperatorDemo.xlsx");
        }
    }
