Not sure if that is possible. Can you not install management studio express to make any changes to your DB?
Yes, you can do many things using server explorer from within visual studio; however, management studio is more appropriate to achieve the same things and there are many things that you can only achieve using management studio but not server explorer.
You can do it in vs 2010 view the table structure, and then look in the properties window of the table. You can change it down there, and then save it, and it modifies the table name. I agree when building a db rapidly it's nice not to even have to open management studio.
