[GRASSLIST:4029] Vector Attribute Table as shown on Screenshots of 5.7

hi folks,

that question may be stupid but anyway: on this screenshot 
http://mpa.itc.it/radim/g51/bridge.png is a table shown. is that within GRASS 
or is it an external programm?
if this is a feature of GRASS, how can make GRASS t oshow me proper tables?

regards,
Florian
