xlsx custom table style

[Aldo Valenti]

With POI 3.7 b2 is it possible to create a custom table style in an xlsx file ?
In the styles.xml part of the xlsx it should render something like

<tableStyles count="1" defaultTableStyle="TableStyleMedium2" 
defaultPivotStyle="PivotStyleLight16">
<tableStyle name="CustomTableStyle" pivot="0" count="2">
      <tableStyleElement type="wholeTable" dxfId="0"/>
</tableStyle>
</tableStyles>

TIA,

Aldo Valenti.
