    //Close the presentation
    presentation.Close();
    'Create an instance of presentation
    Dim presentation__1 As Presentation = TryCast(Presentation.Create(), Presentation)
    'Add slide to the presentation
    Dim slide As ISlide = presentation__1.Slides.Add(SlideLayoutType.Blank)
    'Add table to the slide
    Dim table As ITable = slide.Shapes.AddTable(3, 3, 100, 120, 300, 200)
