I don't have this configuration, yet I haven't changed the default 
configuration.
Value:
(("verbatim" current-indentation)
  ("verbatim *" current-indentation)
  ("filecontents" current-indentation)
  ("filecontents *" current-indentation)
  ("tabular" LaTeX-indent-tabular)
  ("tabular *" LaTeX-indent-tabular)
  ("align" LaTeX-indent-tabular)
  ("align *" LaTeX-indent-tabular)
  ("array" LaTeX-indent-tabular)
  ("eqnarray" LaTeX-indent-tabular)
  ("eqnarray *" LaTeX-indent-tabular)
  ("displaymath")
  ("equation")
  ("equation*")
  ("picture")
  ("tabbing"))

Indentation in an environment is controlled by a function. I find that
the LaTeX-indent-tabular function is not very satisfactory in some
cases. The solution would be to write a function that does what you
want, but that's Emacs-lisp code.  It is one of the easiest computer
languages to learn and use that I know ...
