You can use this styling:

But since you can't edit the tabs directly, you'd need to put the tabber in a container with a class indicating which tab is hidden, then use CSS to apply the styling. Or perhaps give hidden tabs a certain title format and use JS to find them and apply the style.

Not sure what the use in hiding a tab is though, it's not really wiki-like.
