        public MainWindow()
        {
            InitializeComponent();
            DV = GenerateDataTable().AsDataView();
            this.DataContext = this;
        }
        DataTable GenerateDataTable()
        {
            dataTable = new DataTable();
            for(int i=0;i<25;i++)
            {
                dataTable.Columns.Add(new DataColumn($"{i+1}"));
            }
            return dataTable;
        }
    }
}
