Microsoft Outlook- Formatting html documents viewed in Outlook

[Nis81]

Hi
I am attempting to use an html document in Outlook as a stationary file. However i have found that the file does not view the same in dreamweaver as in Outlook. Basically i have used a table in my stationary document and it seems to lose one cell when viewed in Outlook. I was wondering if anyone could explain how stationary works in Outlook and how unexpected formatting errors in outlook can be minimised.

Hope that makes sense

Thanks,
