Help needed regarding table layouting Issue in CS4

I was trying to layout a table using an Indesign custom script in CS4. The input to the Indesign is a XML file

Please find below the snapshot of the XML file with the table definition:

<Table xmlns="http://ns.adobe.com/AdobeInDesign/5.0/" aid5:tablestyle="_XXY" aid:tcols="6" aid:trows="17"><Cell xmlns:aid5="http://ns.adobe.com/AdobeInDesign/5.0/" aid5:cellstyle="_XYY" aid:ccols="1" aid:crows="1" aid5:tablestyle="_XXY">

Now when the table is layouting it is not taking into account the style of the table nor that of the cell.

Can you please suggest what is the best way of defining the table styles and the cell styles so that the table can be laid out in Indesign with the proper table styles and the cell styles.
