Let's zoom out a bit.

`org-babel-string-read' is used exclusively by `org-babel-import-elisp-from-file'

Its effect is making the following tables look same for Org babel:

| 1 | 2 |
| 1 | 2 |

| "1" | "2" |
|  1  |  2  |

I cannot find justification - this behavior has been introduced in ob-R
from the very beginning (over 15 years ago) and then ported to ob-core.

IMHO, the current behavior is not correct. Moreover, it is unexpected.

Consider

#+begin_src C :results output table :includes <stdio.h>
printf("1 2\n\"1\" \"2\"");
#+end_src

#+RESULTS[30c03a8e3f8a71e03d7892e6817cb45713bec424]:
| 1 | 2 |
| 1 | 2 |

Why are the quotes dropped?

And replacing the call to org-babel-string-read with org-babel-read does not
break any tests...
