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
     | Area/Month    |   Jan |   Feb |   Mar |   Sum |
     |---------------+-------+-------+-------+-------|
     | /             |     < |       |       |     < |
     | <l13>         |  <r5> |  <r5> |  <r5> |  <r6> |
     | North America |     1 |    21 |   926 |   948 |
     | Middle East   |     6 |    75 |   844 |   925 |
     | Asia Pacific  |     9 |    27 |   790 |   826 |
     |---------------+-------+-------+-------+-------|
     | Sum           |    16 |   123 |  2560 |  2699 |

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.
