A recent quick test indicates that with RH7 you can specify
the borders from the CSS stylesheet. That did not override existing
inline colours but that should not be an issue for you.
I cannot guarantee it will work for your tables and it might
be necessary to go to each table and apply a table class. There's
probably a way of doing that using a find and replace tool.
It depends on your knowledge of CSS and confidence in
undertaking multi file find and replace operations.
Whatever you do, make a backup first. Unless of course you
want to be looking for a new job!
