[Orgmode] orgtbl-mode-map is missing TAB-related bindings

[sand]

The Emacs 23 org-table.el library (6.21b) includes a binding for
org-table-previous-field:

    (org-defkey orgtbl-mode-map [(shift tab)]
      (orgtbl-make-binding 'org-table-previous-field 104
                           [(shift tab)] [(tab)] "\C-i"))

On both my work and home machines, Shift+TAB generates the event
<S-iso-lefttab>, which is then translated to <backtab>.  The above
binding does not match those events.  For comparison, the org-mode-map
definition has complete coverage:

  (unless (featurep 'xemacs)
    (org-defkey org-mode-map [S-iso-lefttab]  'org-shifttab))
  (org-defkey org-mode-map [(shift tab)]    'org-shifttab)
  (define-key org-mode-map [backtab] 'org-shifttab)

Can someone add the necessary bindings to orgtbl-mode-map?

Thanks,

Derek
