PowerPoint Table Formatting in C# and VB.NET

Whenever you need to display data organized in columns and rows in your presentations, you can insert and format tables.

In GemBox.Presentation, table-formatting options can be specified for tables and table cells, using your C# and VB.NET applications.

With the following example, you will learn how you can create a formatted table.
