Adding HTML grid to PurchTableDocument placeholder in AX 2012

Hi All

I am trying to create an HTML grid to be displayed in workflow notification email for Purchase order workflow. 

I have created a custom placeholder that contains HTML tags to create a grid and place the values inside that. 

But I am receiving the Email like this:

<TABLE id=table1 cellSpacing=2 cellPadding=2 border=1><TBODY><TR><TH>Line Num</TH>< ;TH>Item ID</TH><TH>Description</TH><TH>Category</TH><TH>Quantity</TH><TH>UOM</TH><TH>Unit Price</TH><TH>Line Amount</TH></TR><TR><TD>1</TD><TD>HDA-031</TD><TD>Blue Genesis DB</TD><TD>Legacy</TD><TD>20,001.00</TD><TD>ea</TD><TD>1.00</TD><TD>20,001.00</TD></TR></TBODY></TABLE>

Can someone please point out what is the correct way to do this?

Thanks much,

Shyamala.
