     * Creates a new TableColumnHeader instance for the given TableColumnBase instance. The general pattern for
     * implementing this method is as follows:
     *
     * 
     *     If the given TableColumnBase instance is null, has no child columns, or if the given TableColumnBase
     *         instance equals the TableColumnBase instance returned by calling {@link #getTableColumn()}, then it is
     *         suggested to return a {@link TableColumnHeader} instance comprised of the given column.
     *     Otherwise, we can presume that the given TableColumnBase instance has child columns, and in this case
     *         it is suggested to return a {@link NestedTableColumnHeader} instance instead.
     * 
     *
     * Note: In most circumstances this method should not be overridden, but in some circumstances it
     * makes sense (e.g. testing, or when extreme customization is desired).
     *
     * @param col the table column
     * @return A new TableColumnHeader instance.
