I don't know what your style is or price range, but here's something.

Here is a link that might be useful: End Table

Have you considered ottomans?? I know you say you wanted a door, but they're very kid friendly. And they can double as seating if you have extra guests over.

I just mention them because I was looking for exactly what you are, for the same reasons. Storage, and kid friendly. I watch little ones all day. I couldn't find what I wanted, so I got one cheapo ottoman to be temporary, and now I have 3! If the kids play around them, they don't get scratched, if they fall back into them, it doesn't hurt them.

I have the ones where the lids can be removed and flipped over and used as a table. That way lamps or pictures can be placed on them.

I'm not sure if thats your style, or if you've already decided against it. Just thought I'd mention an alternative if you can't find what you're looking for.

a Google or Shop.com search on: "end table" + door (or perhaps "side table" + door)

will find you lots of ideas.

That www.homedecorators.com link above is to a site with lots of mail order tables in many different styles--ornate European carving; painted American country; etc.; I've used some of their "assemble it yourself" stuff, and it's just fine.
