Hi,
You can add the following lines of code where-ever  you want to add the table:
    IWDTransparentContainer tr = (IWDTransparentContainer) viewObj.getElement("trans");  // Container where table will be added 
     IWDTable tab = (IWDTable) viewObj.createElement(IWDTable.class ,"Table ID");
     tr.addChild(tab);
     IWDNodeInfo nodeInfo = wdContext.nodeProducts().getNodeInfo();
     tab.bindDataSource(nodeInfo); // datasource of your table.
     // First Column
     IWDTableColumn tc1 = (IWDTableColumn) viewObj.createElement(IWDTableColumn.class, "TC1");
     IWDCaption cap1 = (IWDCaption) viewObj.createElement(IWDCaption.class,"cap1");
     cap1.setText("Column Heading 1"); // name1 of your column
     tc1.setHeader(cap1);
     IWDInputField inp1 = (IWDInputField) viewObj.createElement(IWDInputField.class,"INP1");
     tc1.setTableCellEditor(inp1);
     IWDAttributeInfo attrInfo1 = wdContext.nodeProducts().getNodeInfo().getAttribute(IPrivateTEST.IProductsElement.PRODUCT_ID);
     inp1.bindValue(attrInfo1);
     tab.addColumn(tc1);
     // Second Column
     IWDTableColumn tc2 = (IWDTableColumn) viewObj.createElement(IWDTableColumn.class, "TC2");
     IWDCaption cap2 = (IWDCaption) viewObj.createElement(IWDCaption.class,"cap2");
     cap2.setText("Column Heading 2");
     tc2.setHeader(cap2);
     IWDInputField inp2 = (IWDInputField) viewObj.createElement(IWDInputField.class,"INP2");
     tc2.setTableCellEditor(inp2);
     IWDAttributeInfo attrInfo2 = wdContext.nodeProducts().getNodeInfo().getAttribute(IPrivateTEST.IProductsElement.NAME);
     inp2.bindValue(attrInfo2);
     tab.addColumn(tc2);
     // Third Column
     IWDTableColumn tc3 = (IWDTableColumn) viewObj.createElement(IWDTableColumn.class, "TC3");
     IWDCaption cap3 = (IWDCaption) viewObj.createElement(IWDCaption.class,"cap3");
     cap3.setText("Column Heading 3");
     tc3.setHeader(cap3);
     IWDInputField inp3 = (IWDInputField) viewObj.createElement(IWDInputField.class,"INP3");
     tc3.setTableCellEditor(inp3);
     IWDAttributeInfo attrInfo3 = wdContext.nodeProducts().getNodeInfo().getAttribute(IPrivateTEST.IProductsElement.DETAILS);
     inp3.bindValue(attrInfo3);
     tab.addColumn(tc3);
For any further doubts you can always come back to me.
thanks & regards,
