I have a large table, and have classes on the TD's I want to toggle. This works fine in IE8, FF, Chrome, etc. However in IE7 and IE6, the class switching on the table doesn't seem to take effect. If I go into the IE developer toolbar, and manually turn the CSS class off and on, it then works, but I have to do that each time.
I found one place suggesting to toggle the visibility and display properties of the table, which is why you'll see the table flash when you click Show 1.
Here is a test page I set up: http://www.athletic.net/Demo/Josh/Test/ClassSwitching.htm
PS - I've also posted this question here:
