hi Anitha,
you have to create a separate value node for storing original elements and their subtotals in the order you want them in the table.
For showing totals you can use cell variant in the table to give a different look and feel for the subtotal row.
Add another attribute in the value node for storing the variant name. bind this attribute to selected cell variant of table column.
int subtotal =0;
for(int i =0;i < size;i++)
IPrivate<view>NodeElement dataElement = dataNode.getDataElementAt(i);
IPrivate<view>NodeElement tablelement = wdContext.node<table>().createElement();
wdCopyService.copycorresponding(dataElement, tableElement);
//set cell variant to blank for original rows
tableelement.setSelectedVariant("");
wdContext.node<table>().addElement(tablelement);
//Calculate subtotals and add them in another valuenode
subtotal = subtotal + dataElement.getAmt();
if(i ==3)// give condition at which you need to add subtotal row.
IPrivate<view>NodeElement subtotalelement = wdContext.node<table>().createElement();
subtotalelement.setSubtotal(subtotal);
//set cell variant for subtotal row
subtotalelementsetSelectedVariant("subtotal");
wdContext.node<table>().addElement(tsubtotalelement);
subtotal =0; //reset subtotal
hope this helps!
