Hi Baoqiu,

  A file with the following contents fails to export to Docbook:

#+begin_src org
  ,* Table with a backslash in it
  
  ,  | \ |
  
#+end_src

It gives the following error 

#+begin_example
  "Invalid use of `\' in replacement text"
#+end_example

The following changes (replace-match literally in
`org-export-docbook-finalize-table') solves this problem for me, but I
would not know whether this would break anything else.
