In a nutshell, you do a lua_getglobal() to retrieve T, then do a 
pushliteral/rawget pair to get "Array", and then pushstring/rawget 
pairs to get individual elements.

Off the top of my head, something like:

lua_getglobal( L, "T" ); // T
lua_getpushliteral( L, "Array" ); // T : "Array"
lua_rawget( L, -2 ); // T.Array
lua_pushnumber( L, whatever ) ; // T.Array : index
lua_rawget( L, -2 ); // T.Array : whatever_was_at_Array[index]

etc. etc.
