rowspans and colspans in html email

Can rowspans and colspans be safely used when designing table-based HTML emails?

I have been told that they don't display correctly in Outlook 2007 and that tables must be n开发者_运维百科ested in order to provide different size cells for layout.

Can anybody help or provide any links? Thanks

Colspans are usually safe to use. Stay away from rowspans.

Your best option is to nest a new table within a cell instead of doing rowspans or colspans.

The problem is, that BlackBerry Browser 4.2 does not support nested tables. http://docs.blackberry.com/en/developers/deliverables/1143/browser_devguide.pdf page 42.

Tables: The browser supports tables. Users can turn on HTML table support to properly display tables that fit within the screen width of the device. Larger tables ar e split apart with the table cells displayed in vertical sequence. Tables cannot be nested within each other. You should test tables thoroughly in the BlackBerry Br owser to verify that they display appropriately on the device.
