Is there an update on this bug? It's been driving me crazy. If this wasn't such an issue, I think I'd be much happier with using tables in Publisher.
That being said, I think I figured out something weird about this. I've been using "No Break" as suggested above, and it seems to help a lot, but it only seems to work sometimes. It seemed like "AutoFit Column to Context" was only "listening" to one row. So, Row 4 had the longest text in Column A, and AutoFit listened to that when applied to Column A. When I try to AutoFit Column B, it seems that AutoFit is still "listening" to Row 4 and AutoFits to that instead of the longer text in Row 3's Column B. Thus, with Row 3 having the longest text again in Column C, AutoFit works fine again for Column C.
Here's the even weirder part: it doesn't always do this. It did this in the original table (that I was actually using), but it didn't do it in the first table that I copied, but then I copied the original table again (and made fewer changes to it) and the problems showed up again!
EDIT: I said it doesn't always do that, but I think there are more rules than I noticed. It seems that AutoFit only "listens" to later rows. So, below, in Row 5's Column B, it AutoFits fine even though Row 4's Column A still has the longer text. However, Row 4's Column C is now broken because AutoFit is listening to a later row (Row 5) at that point. So, AutoFit on Column A listens to Row 4, AutoFit on Column B listens to Row 5, but AutoFit on Column C is being weird—it doesn't seem to be listening to anything.
But it gets weirder! Because "Evenly Distribute Columns" seems to get stuck. If I hit that button (for all of the columns at the same time), then, even if I resize the columns (which I have to do through the Table menu and I can only make them bigger for some reason), then, if I AutoFit, they just Distribute instead.
