jquery: How can I prevent click event in the inner div

[zNk]

I have MS Excel WebApp document embeded in my web page using JavaScript option (not an iframe).I want to prevent users to click on the cells and selecting them this way (at least for some columns).But when I make a jquery function which catches a click in the outer Excel div,nothing happens because some inner div of some cell of the Excel table catches it. Problem is, that I can't change (remove click functions) the content of the embeded Excel document, because it is generated automaticaly.So the question is: How can I prioritize the outer div click funcion and prevent to fire a click event on the inner div without changing the content of the inner div?Thanks
