Dear developers

When exporting a document containing a table and using the :rel-width
modifier (as documented in [info:org#Tables in ODT export]), an error is
returned:

     #+ATTR_ODT: :rel-width 50

OpenDocument export failed: Format specifier doesn't match argument type

Reason is that the plist-get in line 1458 of ox-odt.el returns a string
reprensentation "50" of the :rel-width number, but the
org-odt-table-style-format
variable contains a %d conversion string for this parameter.

      (loop for (style-name props) in
    (plist-get org-odt-automatic-styles 'Table) do
    (when (setq props (or (plist-get props :rel-width) 96))
      (insert (format org-odt-table-style-format style-name props))))

Either the conversion string should be changed to a %s or the plist-get
obtained value should get converted to a string.
