   * LightTable is a light-weight collection table implementation that supports a subset of features,
   * Current known supported features are:
   *
   * <ul>
   * <li>DataField</li>
   * <li>InputField with TextControl, CheckboxControl, or single SelectControl</li>
   * <li>MessageField</li>
   * <li>LinkField</li>
   * <li>ActionField</li>
   * <li>ImageField</li>
   * <li>most RichTable options</li>
   * <li>FieldGroup containing only Actions, Image, Messages, or Links</li>
   * <li>SpringEL for String properties on supported components only</li>
   * <li>SpringEL specifically for the render property</li>
   * </ul>
   *
   * Other features are not guaranteed to work, but may work at your own risk.  The intent of this table is to be a
   * light-weight alternative to the fully featured table already available in KRAD and it is more suited to displaying
   * large sets of simple data to the user.
