Привязать ширину столбца программно в UWP?

Я пытаюсь создать столбцы, размер которых может быть изменен пользователем во время выполнения, как в Excel. Однако я динамически создаю поля и не знаю, как привязать ширину программно созданного столбца к ширине моего столбца, созданного в xaml.

Вопрос. Как привязать ширину столбца программно, а не в XAML?

cs:

public sealed partial class WepPage : Page
    {
        static int i = 0;
        Grid grid;
       
        
    public WepPage()
    {
        this.InitializeComponent();
   
    }
    private void AddWepButton_Click(object sender, RoutedEventArgs e)
    {
        addWepStack();    
    }
    private void addWepStack()
    {
       
        grid = new Grid();
        grid.Name = ("ItemGrid" + i.ToString()); 
        WepStackPanel.Children.Add(grid);
        //create columns
        ColumnDefinition col0 = new ColumnDefinition();
        ColumnDefinition col1 = new ColumnDefinition();
        ColumnDefinition col2 = new ColumnDefinition();
        ColumnDefinition col3 = new ColumnDefinition();
        ColumnDefinition col4 = new ColumnDefinition();
        ColumnDefinition col5 = new ColumnDefinition();
        // Set the width of each column
       
        //HERE IS WHERE I WANT TO BIND THE COLUMN WIDTH TO THE WIDTH OF THE HEADERS 
        //SO THE USERS CAN CHANGE THE COLUMN WIDTH WHILE THE APPLICATION IS RUNNING.

        // Add columns to grid
        grid.ColumnDefinitions.Add(col0);
        grid.ColumnDefinitions.Add(col1);
        grid.ColumnDefinitions.Add(col2);
        grid.ColumnDefinitions.Add(col3);
        grid.ColumnDefinitions.Add(col4);
        grid.ColumnDefinitions.Add(col5);

        i++;
    }

}
