How to use Node.js in windows 8 javascript app

I read both of these thread:

http://social.msdn.microsoft.com/Forums/en-US/winappswithhtml5/thread/8c9a840a-91a5-4d50-88fc-8ba346c8c387

Which make me confused!

what I want to do is create a Azure table storage in windows 8 app.

But by learn Mobile service I only find this sample:

http://code.msdn.microsoft.com/Use-Table-Storage-in-0b6bcbc7/sourcecode?fileId=79395&pathId=418377534

It seems I can only CRUD storage tables with Mobile service with Node.js.

But I don't know how to create a table in that server script.

I want to use some thing like this:

http://www.windowsazure.com/en-us/develop/nodejs/tutorials/web-app-with-storage/

How can directly use this in windows 8 app?
