I can only give a 5.2 answer but this a very basic question.

Say you have already got your new empty table on the stack in register t.
Then one field at a time, push the value on the stack and lua_setfield it.

E.g.

lua_newtable(L);  {* table is now in -1 *}
lua_pushinteger(L,1); {* table is now in -2 *}
lua_setfield(L,-2,"a");
lua_pushinteger(L,2); {* table is now in -2 *}
lua_setfield(L,-2,"b");
