Hello

I've been playing around with this for a while now and well, just to make sure I'm not going nuts I need to know this.
When using datavalidation with a List it is possible to type whatever you want if the List includes at least one empty cell. I consider this a useful feature.
However, if you have created a table and applied some datavalidation with a list, it won't let you type whatever even if the List contains an empty cell. I wish it would.
Is there a way around this? Any comments in general?
