Create PowerPoint tables in C# and VB.NET

Table elements are used to present content in a rectangular grid, separating data into columns and rows.

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.

In the GemBox.Presentation API, the table-related types are grouped in the GemBox.Presentation.Tables namespace.

With the example below, you will learn to create and populate a simple table using the GemBox.Presentation API.
