I not positive even after reading about the sytle sheets how I can change just a single table look.
what I want is to override the background on tabs in special cases.

I see it's using .tundra .dijitTab so I want to create my own back ground tabPendingDisabled.png and tabPendingEnabled.png and use these on some tabs but not all tabs.

I think I would want to define this in my own style sheet in order that I keep the dojo files as is.
