I'm wondering if you're just running into different ways that different apps handle the same formatting code.

If you make the table from scratch in the destination application does it look like the same table in OneNote?
 
If the two different apps display the same code/formatting differently then your desired result is probably not going to happen.

Web designers deal with this every day as the pages they design are displayed differently on just about every web browser they test.
