	 * The TablePersoDialog can be used to display and allow modification of personalization settings relating to a Table. It displays the columns of the table that it refers to by using

	 * <li>the column header control's 'text' property if no caption property is available</li>
	 * <li>the column header control's 'title' property if neither 'text' nor 'caption' property are available</li>
	 * <li>the column id is displayed as last fallback, if none of the above is at hand. In that case, a warning is logged. </li></ul>
	 *
	 * @deprecated since 1.115. Please use the {@link sap.m.p13n.Popup Popup} for personalization instead.
