I'm using LaTeX Plugin 0.2 rc2. What happend to option Insert Tabulra Object which allowed to import tabular from file http://panoramix.ift.uni.wroc.pl/~qpalzm/s1.png . It was one of the coolest options and i hope i'm just blind and it's still available.
This is gone because it was quite hacky… but I think about bringing it back in a more powerful way. See https://sourceforge.net/tracker/?func=detail&aid=2979405&group_id=204144&atid=988431
