    public class ISmartMarkerCallBackDemo : ISmartMarkerCallBack
    {
        // Implementing the Process method from ISmartMarkerCallBack interface
        public void Process(int sheetIndex, int rowIndex, int colIndex, string tableName, string columnName)
        {
            // Example implementation of the Process method
            Console.WriteLine($"Processing sheetIndex: {sheetIndex}, rowIndex: {rowIndex}, colIndex: {colIndex}, tableName: {tableName}, columnName: {columnName}");
        }

        public static void ISmartMarkerCallBackExample()
        {
            // Create a new WorkbookDesigner instance
            WorkbookDesigner designer = new WorkbookDesigner();
            // Open a template file (which contains smart markers)
            designer.Workbook = new Workbook("ISmartMarkerCallBackExample_original.xlsx");

            // Set the callback interface
            designer.CallBack = new ISmartMarkerCallBackDemo();

            // Initialize your data from data source
            // For demonstration, we will use a simple DataTable
            System.Data.DataTable dataTable = new System.Data.DataTable("Table1");
            dataTable.Columns.Add("Column1", typeof(string));
            dataTable.Rows.Add("Value1");
            dataTable.Rows.Add("Value2");

            // Set the datatable as the data source
            designer.SetDataSource(dataTable);

            // Process the smart markers to fill the data into the worksheets
            designer.Process(true);

            // Save the excel file
            designer.Workbook.Save("ISmartMarkerCallBackExample.xlsx");
