Is there an equivalent of CSS max-width that works in HTML emails?

I'm trying to create an HTML email that will display properly in all widely used email clients. I'm wrapping the whole email in a table, and I'd like it to have a width that is up to 98% of the available width, but no greater than 800 pixels. Like this: <table style="width:98%; max-width:800px;">

But I'm not doing it that way, since according to this Outlook 2007 does not support the CSS width property.

Instead, I'm doing this: <table width="98%">

Is there any way to also set a max-width without relying on CSS?
