I couldn't find a way to export a table to Excel in a recent new install of Acad MEP 2012 from either the ribbon or right click menus. ...maybe operator error... anyway I had spent a lot more time than I wanted looking for the command "The new improved way".
I found I was able to export a table using "TABLEEXPORT" at the command prompt. I was going one direction only, out to Excel. I chose a .csv file format.
When importing back top Excel I used comma separated for the import operation. It worked great.
I hope this helps someone else who is trying to get by out there.
