This code block defines the == form used to read table references
without conversion.  Eval this first.
#+begin_src emacs-lisp :results silent
  (defmacro with-simple-tables (ref)
    `(flet ((org-babel-read-table () (org-table-to-lisp)))
       (org-babel-ref-resolve ,(symbol-name ref))))
#+end_src

* Original Example
#+TBLNAME: table_test
| name  |  id |
|-------+-----|
| name1 | 034 |
| name2 | 135 |
| name3 | 1B5 |

#+NAME: code_test_orig
#+BEGIN_SRC emacs-lisp :var table=table_test
  (format "%S" table)
#+END_SRC

#+RESULTS: code_test_orig
: (("name" "id") hline ("name1" 34) ("name2" 135) ("name3" "1B5"))

and now without conversion

#+NAME: code_test_simplified
#+BEGIN_SRC emacs-lisp :var table=(with-simple-tables table_test)
  (format "%S" table)
#+END_SRC

#+RESULTS: code_test_simplified
: (("name" "id") hline ("name1" "034") ("name2" "135") ("name3" "1B5"))
