Revision 1.144, Thu Jan 13 14:30:13 2011 UTC (13 years, 8 months ago) by kristaps
Branch: MAIN
Changes since 1.143: +20 -4 lines
Change how -Thtml behaves with tables: use multiple rows, with widths
set by COL, until an external macro is encountered. At this point in
time, close out the table and process the macro. When the first table
row is again re-encountered, re-start the table. This requires a bit of
tracking added to "struct html", but the change is very small and
follows the logic of meta-fonts. This all follows a bug-report by
joerg@.
