Simple question 2 about input on wizards

Version: Windchill 12.1

Use Case: I need to gather user inputs in a Wizard.

Description:

Thanks to @avillanueva and @BjoernRueegg and this post https://community.ptc.com/t5/Windchill-Customization/Likely-very-simple-question-about-input-on-wizards/m-p/865207#M1969%3Fsource=search I am in the process of creating my own AttributePanelConfig.

My problem is that I can't find the right combination of ComponentType so the label and the input are aligned horizontally. So far all I can get is aligned vertically. Screenshot of what I am getting:

and screen shot of the ootb New Part wizard attributes, note the Label and the input are aligned horizontally, which is how I want mine to look like:

The following is what I am using for buildComponentConfig() and buildComponentData()

@Override
	public ComponentConfig buildComponentConfig(ComponentParams params) throws WTException {

		ComponentConfigFactory factory = getComponentConfigFactory();

		JcaAttributePanelConfig attributePanelConfig = (JcaAttributePanelConfig) factory.newAttributePanelConfig();
		//ComponentType.WIZARD_ATTRIBUTES_TABLE
		//ComponentType.WIZARD_TABLE
		//ComponentType.ATTRIBUTE_PANEL
		//attributePanelConfig.se
		attributePanelConfig.setComponentType(ComponentType.WIZARD_ATTRIBUTES_TABLE);

		JcaGroupConfig groupConfig = (JcaGroupConfig) factory.newGroupConfig("customConfig1");
		//ComponentType.WIZARD_ATTRIBUTES_TABLE
		//ComponentType.WIZARD_TABLE
		groupConfig.setComponentType(ComponentType.WIZARD_ATTRIBUTES_TABLE);
		//groupConfig.setIsGridLayout(true);
		groupConfig.setIsMultiColumnGridLayout(true);
		groupConfig.setLabel("Input");
		groupConfig.setRenderOnTop(true);

		AttributeConfig input1 = factory.newAttributeConfig("input1", "Input1 Testing");
		input1.setComponentType(ComponentType.WIZARD_ATTRIBUTES_TABLE);
		groupConfig.addComponent(input1);

		AttributeConfig input2 = factory.newAttributeConfig("input2", "Input2 Testing");
		input2.setComponentType(ComponentType.WIZARD_ATTRIBUTES_TABLE);
		groupConfig.addComponent(input2);

		attributePanelConfig.addComponent(groupConfig);

		return attributePanelConfig;
	}

	@Override
	public Object buildComponentData(ComponentConfig config, ComponentParams params) throws WTException, ParserConfigurationException, SAXException, IOException {

		Map<String, AbstractGuiComponent> guiMap = new HashMap<String, AbstractGuiComponent>();

		// input test 1 with giu array
		GUIComponentArray guiArray = new GUIComponentArray();
		guiArray.setDelimiter(Delimiter.SPACE);
		TextBox input1 = new TextBox();
		input1.setId("input1");
		input1.setName("input1");
		input1.setWidth(5);
		guiArray.addGUIComponent(input1);
		IconComponent icon = new IconComponent("wtcore/images/part.gif");
		icon.setTooltip("Hello World");
		guiArray.addGUIComponent(icon);
		guiMap.put("input1", guiArray);

		// input test 2 selection
		ArrayList<String> displayList = new ArrayList<String>();
		ArrayList<String> internalList = new ArrayList<String>();
		ArrayList<String> selectedValue = new ArrayList<String>();
		displayList.add("Value 1");
		displayList.add("Value 2");
		displayList.add("Value 3");
		internalList.add("value1");
		internalList.add("value2");
		internalList.add("value3");
		ComboBox comboBox1 = new ComboBox(internalList, displayList, selectedValue);
		comboBox1.setId("comboBox1");
		comboBox1.setName("comboBox1");
		comboBox1.setMultiSelect(false);
		comboBox1.setMultiValued(false);
		guiMap.put("input2", comboBox1);

		return guiMap;
	}

 Anybody have any hints as the what I am missing to get these to align horizontally?
