I assume you mean this kind of tables: { "foo", "bar" }
These are regular tables. Only the keys are the numbers 1, 2, ...
lua_newtable(state);
lua_pushnumber(state, 1);
lua_pushnumber(state, lastworld->active);
lua_settable(state,-3);
or:
lua_newtable(state);
lua_pushnumber(state, lastworld->active);
lua_rawseti(state, -2, 1); // the 1 is the numeric index

Same as above:
lua_pushstring(state, "active");
lua_gettable(state, <tableindex>);
or
lua_pushnumber(state, 1);
lua_gettable(state, <tableindex>);
or
lua_rawgeti(state, <tableindex>, 1); // get field nr 1
or iterate over all elements using lua_next().
