    using Aspose.Cells;
    using Aspose.Cells.Tables;
    using System;

    public class ListColumnCollectionDemo

            Worksheet worksheet = workbook.Worksheets[0];
            Cells cells = worksheet.Cells;

            // Populate the worksheet with some data
            for (int i = 0; i < 5; i++)

                cells[0, i].PutValue(CellsHelper.ColumnIndexToName(i));
            }
            for (int row = 1; row < 10; row++)
            {

            // Add a ListObject (table) to the worksheet
            ListObjectCollection tables = worksheet.ListObjects;
            int index = tables.Add(0, 0, 9, 4, true);
            ListObject table = tables[index];

            // Access the ListColumnCollection of the ListObject
            ListColumnCollection listColumns = table.ListColumns;

            // Demonstrate accessing properties of ListColumnCollection
            Console.WriteLine("Number of columns in the table: " + listColumns.Count);

            // Access individual ListColumn by index
