  /**
   * Renders a table cell in the main JTable. As a TableCellRenderer, we have to implement this
   * method, but we use it to colour different types of matches in different ways. Remember that
   * this is run every time a cell is displayed on the screen, so it needs to be as fast as can be.
   *
   * @param table The table which needs rendering.
   * @param value The object which needs rendering. For now, this can only be a Name object, but
   *     later on we might colour different types of cells in different ways.
   * @param isSelected Is this cell selected, i.e. is the row selected?
   * @param hasFocus Is this cell focused, i.e. is this individual cell selected?
   * @param row The row coordinate of this cell.
   * @param column The column coordinate of this cell.
   * @return A component representing this cell.
