  /**
   * Adjust column widths in an HTML table.
   *
   * <p>The specification of column widths in CALS (a relative width plus an optional absolute
   * width) are incompatible with HTML column widths. This method adjusts CALS column width
   * specifiers in an attempt to produce equivalent HTML specifiers.
   *
   * <p>In order for this method to work, the CALS width specifications should be placed in the
   * "width" attribute of the &lt;col>s within a &lt;colgroup>. Then the colgroup result tree
   * fragment is passed to this method.
   *
   * <p>This method makes use of two parameters from the XSL stylesheet that calls it: <code>
   * nominal.table.width</code> and <code>table.width</code>. The value of <code>nominal.table.width
   * </code> must be an absolute distance. The value of <code>table.width</code> can be either
   * absolute or relative.
   *
   * <p>Presented with a mixture of relative and absolute lengths, the table width is used to
   * calculate appropriate values. If the <code>table.width</code> is relative, the nominal width is
   * used for this calculation.
   *
   * <p>There are three possible combinations of values:
   *
   * <ol>
   *   <li>There are no relative widths; in this case the absolute widths are used in the HTML
   *       table.
   *   <li>There are no absolute widths; in this case the relative widths are used in the HTML
   *       table.
   *   <li>There are a mixture of absolute and relative widths:
   *       <ol>
   *         <li>If the table width is absolute, all widths become absolute.
   *         <li>If the table width is relative, make all the widths absolute relative to the
   *             nominal table width then turn them all back into relative widths.
   *       </ol>
   * </ol>
   *
   * @param context The stylesheet context; supplied automatically by Xalan
   * @param xalanNI
   * @return The result tree fragment containing the adjusted colgroup.
