I have mentioned this to the bugs address for Mosaic, but I guess
they're too busy to do anything with it at the moment. The HTML spec
says:

Within a PRE element,
.
.
.
Anchor elements and character highlighting elements may be used.
.
.
.
NOTE: HIGHLIGHTING

Within a preformatted element, the constraint that the rendering must be on
a fixed horizontal character pitch may limit or prevent the ability of the
renderer to render highlighting elements specially.

This suggests to me that if you can't provide fixed-width characters,
then it is better not to do any highlighting within the <PRE> section.

My situation is similar. I am formatting tables for the man2html
converter, and it is convenient to use <PRE> to do this formatting.
If one column is bolded, though, you end up with jagged columns, due
to the differing widths of the bold characters.

<PRE>
<B>WW</B> some information about WW
<B>ii</B> some information about ii
</PRE>

Keep up the good work, NCSA,
rik.
