Hopefully I understood your question correctly. My solution to "setup"
code blocks is use the noweb syntax. Following is an example with Gnuplot.


  #+PROPERTY: noweb yes
  #+PROPERTY: results silent
  #+BIND: org-confirm-babel-evaluate nil

  * Gnuplot source
  #+name: preamble
  #+begin_src gnuplot
    reset
    set terminal pdfcairo color size 21cm,14.8cm
    set termoption enhanced
    set encoding utf8
    set termoption font "DejaVuSerif,8"
    # ...
  #+end_src

  #+begin_src gnuplot :noweb yes :var limits=Bpluslimits
    <<preamble>>
    plot "$limits" using 1:2 title 'Theory'  set output
  #+end_src

  * Table
  #+tblname: Bpluslimits
  |   |  Theory |
  |   |         |
  |---+---------|
  | 1 | 3.6E-14 |
  | 2 | 3.6E-14 |
  | 3 | 6.3E-13 |
  | 4 | 6.3E-13 |
  | 5 | 1.7E-14 |
  | 6 | 1.7E-14 |
  | 7 |         |
  #+tblfm: $1=(@#-2)

  * COMMENT local setup

  # Local Variables:
  # org-export-allow-BIND: t
  # End:

HTH
