    public class ColGroup
extends org.apache.wicket.markup.html.panel.Panel
    A panel that renders <colgroup> with <col> elements inside it. The columns can be used to style the whole table column.

    Important: this component requires MarkupSettings.getStripWicketTags() to return true, otherwise the browsers break the rendering of the HTML elements. For example Google Chrome renders two <colgroup> elements.
