Enabling/Disabling Toolbar items

I think the description my problem was not clear. I know how to customize toolbars in terms of showing a defined set of toolbar items. However, I can't figure out how to set up the toolbar so certain items are initially enabled or disabled.

For example, the following toolbar set definition displays the "Show Table Borders" and "Show Details" toolbar items initially enabled:

config.ToolbarSets["Minimal"] = [ ['ShowTableBorders','ShowDetails']
] ;

How would I create the same toolbar set, but with each toolbar item initially disabled?

More clarification....

When I say enabled/disabled what I mean is pressed/unpressed. Sorry for any confusion. Thanks again.

I've read all the instructions, tried a few fixes, but nothing has worked. I am not able to turn off (using the customization files or programatically) the ShowTableBorders or ShowDetails options. Sure, I can remove these toolbar items from the toolbar by modifying fck_config.js, but this doesn't change the fact that the content I am showing in FCKeditor still shows up with all those small newline images scatterd throughout the content, meaning that when the editor is loaded, the ShowDetails option is on.

It seems like this should be an easy fix, but it's got me stumped. I'd appreciate any help. Thanks.
