Adding table to a new slide in Powerpoint

Hi,

You can use OpenXmlSdkTool.exe. This tool generates Open XML SDK source code based on document content. The source code could be used to regenerate all or part of the document. So you can design a PowerPoint with a table and then open that presentation in OpenXMLSDktool and get the code to generate it.

The tool can be downloaded from : http://www.microsoft.com/downloads/details.aspx?FamilyId=C6E744E5-36E9-45F5-8D8C-331DF206E0D0&displaylang=en
