Bug 122687 Libraries dont appear to allow background colors on tables to be used
If I create a table and set the background color to blue in my library and then drag the table from the library to the report the background color does not go with it.

* <p>
 * <ul>
 * <li>The {@link #setExtendsElement}method sets the parent element.</li>
 * <li>The {@link #setExtendsName}method sets the name of the parent element.
 * It is used when reading a design file, or if it is necessary to store an
 * unresolved parent name.</li>
 * <li>The {@link #getExtendsElement}method gets the parent element.</li>
 * <li>The {@link #extendsRef}member stores the reference to the parent
 * element.</li>
 * </ul>
 * 
 * <h3>User-Defined Properties</h3>
 * 
 * As noted above, the user can define user-defined properties for an element.
 * User-defined properties have many of the same attributes as system-defined
 * properties. User-defined properties work virtually the same as system-defined
 * properties, including support for localization, for a property type, for
 * validating the property value, and more.
 * <p>
 * Members and classes in the user-defined property system include:
 * <p>
 * <ul>
 * <li>The {@link #addUserPropertyDefn}method defines a user-defined property.
 * </li>
 * <li>The {@link #dropUserPropertyDefn}method removes a user-defined
 * property.</li>
 * <li>The {@link #getUserPropertyDefn}method gets the definition of a
 * user-defined property.</li>
 * <li>The {@link UserPropertyDefn}class defines a user-defined property.
 * </li>
