[bug] org-caldav-sync broken if entries have tables?

[Eric S Fraga <e.fraga@ucl.ac.uk>]

Hello,

I have just upgraded both org and org-caldav and now I can no longer
sync to my Google calendar.  I get the following error:

Debugger entered--Lisp error: (args-out-of-range [left left right left] 4)
  org-export-table-cell-alignment((table-cell (:begin 49232 :end 49241

  org-caldav-sync()
  call-interactively(org-caldav-sync nil nil)
  command-execute(org-caldav-sync)

  
There is nothing particularly strange about the table found at location
49232 in my diary.

Deleting the table and one other, possibly leaving no tables in my
diary, allows syncing to work again.

thanks,
eric
