ejc-eval-org-snippet should return org table if possible

[maxevtushok]

Currently If I eval code block in babel, it returns string, not org-table (list of lists), so it's not possible to use results of this block as an input in another block, like this:

#+name: dboutput
#+begin_src sql :results table
  select ('2023-08-14 06:32:00'::DateTime)::int * 1000 as a,
         ('2023-08-14 06:36:00'::DateTime)::int * 1000 as b
#+end_src

#+begin_src shell :var input=dboutput[2,0]
  echo ${input}
#+end_src

What I propose - is to try to return org-table if it is possible or string, if not (for working with error messages)

@maxevtushok Thank you for this propose. Please create a pull request for it. I guess it can be simplified a little:

       (if ejc-org-mode-show-results
           (with-temp-buffer
             (insert-file-contents (ejc-get-result-file-path))
-            (buffer-string))))))
+            (or (org-babel-read-table)
+                (buffer-string)))))))
