This is a fork from freqdec's slabtext jQuery plugin. The Slabbing algorithm has been rewritten, from scratch, to support vertical heights and better optimize page space usage
This happens with all browsers, plugin is not applying postTweak as expected. As you can see on image attached, line with 'records: 12' is outside of the DIV it is inside (blue rectangle). If the postTweak was applied, letter-spacing in the negative would solve the issue, but that doesn't happen.
