How to create and render custom table for non persistable object in windchill?

This should work

import com.ptc.mvc.components.*;
import wt.util.WTException;

import java.util.ArrayList;
import java.util.List;

public class MyTableBuilderClass extends AbstractComponentBuilder {
 @Override
 public ComponentConfig buildComponentConfig(ComponentParams arg0) throws WTException {
 ComponentConfigFactory factory = getComponentConfigFactory();
 TableConfig table = factory.newTableConfig();
 table.setLabel("User Info..");
 table.setSelectable(true);

 table.addComponent(factory.newColumnConfig("context", "Context", true));
 table.addComponent(factory.newColumnConfig("contextTeamRole", "Context Role", true));
 table.addComponent(factory.newColumnConfig("fromUser", "From User", true));
 table.addComponent(factory.newColumnConfig("toUser", "To User", true));
 
 ColumnConfig columnConfig = factory.newColumnConfig("oid", "oid", false);
 columnConfig.setDataStoreOnly(true);
 table.addComponent(columnConfig);
 return table;
 }
 
 @Override
 public Object buildComponentData(ComponentConfig arg0, ComponentParams arg1) throws Exception {
 List<UserUtil> result = new ArrayList<UserUtil>();
 result.add(new UserUtil("Product1", "Member", "User1", "User2","1"));
 result.add(new UserUtil("Library2", "Member", "User1", "User2","2"));

 result.add(new UserUtil("Library4", "Member", "User1", "User2","4"));
 result.add(new UserUtil("Project5", "Member", "User1", "User2","5"));
 for (UserUtil userUtil : result) {
 System.out.println("Context : " + userUtil.getContext());
 }
 return result;
 }
 // POJO : User Utility
