Access to the "jc" table property for table centring

[gkholman]

Per the ECMA specification

17.4.26 jc (Table Alignment Exception)

[Example: Consider the following WordprocessingML fragment for a table in a document:
  <w:tblPr>
    <w:jc w:val="center" />
</w:tblPr>
This table is now centered on the page. end example]````

Is there SWPX vocabulary available for us to specify that a table is centred?
