All you need to do is get her attention. I use to frequent book stores/coffee shops with my own books, or magazines as props. Whatever it was, I could talk about it when asked.
I sit withing a close enough distance where she can easily see and hear me. I start reading for a few minutes and then I let out a laugh, then a little later another one, a little louder. Women are generally curious (especially about guys who are jovial and in a good mood) so there is a chance that she will ask you what was so funny.
If she doesn't, just put down your book and call to her, "Excuse me, what do you think..
Money is the root of all evil OR The love of money is the root of all evil?" You can use any topic that you are will versed in but will still pique her interest.
She'll either give you her thought or she will give you a quizzical look. Either way, you can directly make your way to her table to discuss the topic further.
The rest is up to you.
