I had the trimming problem occurring on a table of an HTML newsletter. It was very important that the entire table display because it was the #1 content our client wanted to communicate. Here's the fix, or at least here's how we solved our problem. We eliminated any repetition. So for this table, the lines in between each row, Gmail was seeing the lines as repetitive. So I altered the pixel width by 1 px every other line, which eliminated the repetition and fixed our problem. So that said, look for repetition, and try to remove it. OR in some cases, you might have to add type (in white) to create the variation. Unfortunately, this new Gmail feature sucks; it forces us to create clunky workarounds. We should be able to control the content of our own emails, not the other way around. Also, this new feature has opened up the door for shoddy email marketing (where some marketers are hiding their unsubscribe links from customers by creating enough repetition so the link gets hidden.)
