Has anyone out there found a workaround or seen any updates to this issue? https://www.campaignmonitor.com/blog/post/3585/iphone-fail-the-trouble-with-table-borders-and-html-email/

Currently I'm working on a client email that has 2 columns/tables with different background colors. Some neighboring content in the 2 columns needs to line up/stretch to the same height as the other. In trying this, I saw that a bgcolor on the table cells was rendering out these annying 1px borders.

The article above says to place questionable content inside another table, but then I lose the flexibilty of my side-by-side content being the same heights.

Any info/advice?
