I think the plugin you are looking for is here:
http://tw.lewcid.org/#TabEditPlugin
Or an alternate method is to put the data for the tabs in the tiddler
w/ the tab view via hidden sections (my method of choice)

I.E. (tiddler title = palette)
<<tabs palettetabs
"Tab 1" "Tab 1 mouseover" palette##~TableExamples
"Tab 2" "Tab 2 mouseover" palette##~TableExamples
"Tab 3" "Tab 3 mouseover" palette##~TableExamples
