I don't disagree that the table is to blame, but it would be helpful if it outputted some warning or even failed altogether if the table is too wide, regardless of whether it is split.
So, why not raise an assertion error here or is is possible for the layout engine to recover from this in some cases? As it stands this seems much harder to debug then it needs to be. There is no external indication that the table width is the cause of this without some digging.
It seems like it would be helpful for a warning log to be generated during building to make tracking this down easier.
P.S. Just so that I don't just sound like a complainer, I think this is an excellent tool. It's obvious the amount of work and thought that has gone into it. Thanks!
