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.

* named style. The derived class overrides the {@link #getStyle()}method to
 * return the style for use by the generic mechanisms.
 * <p>
 * An element that can have a style is called a <em>styled element</em>. The
 * style affects the styled elements in three distinct ways.
 * <ol>
 * <li>The element can include some or all of the properties defined for the
 * style element. The element defines only those that make sense for that
 * element. These <em>style properties</em> appear as if they are properties
 * of the element itself.</li>
 * <li>The element can name a shared style from which to get properties.</li>
 * <li>If element does provide the value for a style property, and the element
 * does not explicitly reference a shared style, then the application will use a
 * <em>property search</em> to find a style implicitly associated with this
 * element. This is a search upward in the containment hierarchy to find either
 * 1) a shared style referenced by a container, or 2) an predefined style
 * associated with the slot or element. For example, a label in a Container in a
 * List's Header slot will use the predefined "list-header" style unless another
 * style is defined on the style or Container.</li>
 * </ol>
 * <p>
 * Members and classes in the style system include:
 * <p>
 * <ul>
 * <li>The {@link #getStyle()}method returns the associated style, if any, for
 * this element as a generic DesignElement.</li>
 * </ul>
