I've seen a couple threads about this on here about the annoying additional padding Gmail iOS adds to the right of the full-width container table in responsive fluid templates, but the most recent one was nearly a year old and the suggested fix didn't seem to work for everyone.

Wondering if anyone has since come up with a better fix, because the following one did not work for me.

u + .body .gwfw { width:100% !important; width:100vw !important; }

<table cellspacing="0" cellpadding="0" border="0" width="100%" bgcolor="#cccccc" class="gwfw">
