/**
 * @class   vtkQtTableRepresentation
 * @brief   set up a vtkTable in a Qt model
 *
 *
 *
 * This class is a wrapper around vtkQtTableModelAdapter.  It
 * performs the following functions:
 *
 * <ul>
 * <li>Keep track of the key column, first data column, and last data column.
 *     Populate the appropriate ivars on the Qt adapter.
 * <li>Assign colors to each of the data series using a vtkLookupTable.
 *     A default lookup table is provided or the user can supply one
 *     using SetColorTable().
 * </ul>
 *
 * The user must supply the following items:
 * <ul>
 * <li>the name of the column that contains the series names,
 * <li>the names of the first and last data columns
 *     (this range should not contain the key column), and
 * <li>(optionally) a vtkLookupTable to use when assigning colors.
 * </ul>
 *
 *
 * @warning
 * Call SetInputConnection with a table connection
 * BEFORE the representation is added to a view or strange things
 * may happen, including segfaults.
