    // Padding must be added to width for columns to make them fully
    // visible in table header.
    final int padding = 10;
    final int widthOfColumnContainingSixCharacterString = widthOfSixCharacterString + padding;
    getColumn("Line").setMaxWidth(widthOfColumnContainingSixCharacterString);

    getColumn("Tree").setPreferredWidth(preferredTreeColumnWidth);
    // Twenty eight character string to contain "Type" column
    final int widthOfTwentyEightCharacterString = fontMetrics.stringWidth("XXXXXXXXXXXXXXXXXXXXXXXXXXXX");
    final int preferredTypeColumnWidth = widthOfTwentyEightCharacterString + padding;
    getColumn("Type").setPreferredWidth(preferredTypeColumnWidth);
}
