Need Help with Unusual Table Behavior

Question

I've been asked to create a table with unusual behaviors, and I'm a little stuck on how to implement it. The table has cells with dates and blanks in it. The following rules need to work:
1. If the cell has a date in it, then:
a. If the user single-clicks on the cell, the cell should be selected. At most, the date could be highlighted and copied, but not changed
b. If the user double-clicks on the cell, a popup window should appear that allows entry of detailed data about the date. This overrides the default behaviors of entering edit mode on double-click.
c. If the user presses F2, the cell should enter edit mode and allow the user to edit or remove the date. This prevents the user from accidently changing an existing date, which is supposed to be a rare occurance anyway.
2. If the cell has no date, then:
a. If the user single-clicks a cell, double-clicks a cell, or uses the keyboard to navigate to a cell and then begins typing, the cell should enter edit mode and allow the user to enter a date. Once a valid date has been entered, the rules for #1 apply.
Optional:
The user can remove a date by clearing the date, but it would be nice if they could select multiple dates for deletion.
Any ideas would be appreciated. Right now, I'm stuck on how to make the cell editable with a single click depending on whether there is a date already in it.

Fair enough, but in all the topics I've seen on this site, I almost never see someone respond once they've been given an answer to their question. Why call me out on it and not everyone else?It's not just you. It's becoming more and more common actually. Here's an example from only yesterday (reply 3):

Now, you may not like this, but the fact remains that this is how this particular forum works, and if you want help from the regulars here it's in your best interest to stick to the forum rules. Arguing about it almost never helps your case. (Personally I don't care much either way, but that's just me and as you can see from my posting history I'm not here very often so my opinion doesn't matter much.)
Finally, if you want help on JTables in particular, camickr is your man, so you might want to stay on his good side :-)In that thread you cited, it's fair to point out that the person never responded, but calling him a louse, etc. was uncalled for and unprofessional. If someone had politely said that I should reply to my other threads, I would have apologized and moved on. However, that's not what happened. I was called out in a way intended to humiliate me for 2 instances, not for my failure to reply, but for failing to reply quickly enough. That's what I found to be so ridiculous, and hence, my sarcasm. In the third instance, perhaps I should have responded with a "thank you" to the second response that I received. I'll take my lumps for that one. I also took offense to the suggestion that I only replied to my previous thread because I wanted help on this one. That was just a baseless accusation.
And for the record, the reason that I'm responding to this topic so quickly is that my email notifications are working this time. I do check my watchlist when I have a question that needs answering, but if I get pulled off onto another task, I may not check it for a while. I can't help that.
