Tables and other content, such as charts or SmartArt diagrams, are embedded in a special kind of drawing, called a GraphicFrame, contained in the SlideObject.Content.

Set PowerPoint table styles

The following example shows how you can use the GemBox.Presentation component to create table styles and assign them to tables.
