Hi J.,
As many here have said, kids being picky or not is as individual as the child. I have 4 boys, two who eat anything and everything, one who grew out of his pickiness and is more willing to try things (but not until he got to college and was forced into eating to not go hungry) and one very picky eater who thinks chicken nuggets, fish sticks and pizza are food groups. The interesting thing about my very picky eater, is that he was exactly like your daughter until he was about 4, then the pickiness set in. I never, and still, don't cater to that. He always had to eat whatever I made and didn't get snacks so he could fill up later, there seemed to be no reason why this happened, it just did.
As to table wars, you'll be in charge of that, if you make food and eating an issue, it will become an issue. If your daughter doesn't want to eat, the more you make a fuss over it, the more fusses will happen. And she will go through periods of time, no matter how good of an eater she remains, where she just may not want to eat. Or she'll get stuck on one or two foods and only want those. When my 22 year old was a toddler and going through this phase my pediatrician told me there wasn't a child on record who had starved themselves to death. They'll eat when they're hungry. Continue to offer him a variety of good foods and he'll get past it - and he did.
I think the main point I'm trying to make here is that no matter how much you do the right thing, your very individual child will eventually make up her own mind about food preferences and the more you accept that, the less of any kind of war - table or otherwise - you'll have.
