One of the problems Felicia is referring to is at:
res/fsu/GeneralChemLib/Lab/InterMolForces/LiquidProperties.problem
I wanted to make the web page compact, so I grouped parts into table cells.
But they don't print well, so Felicia suggested I wrapped all the table tags
in <web></web> tags, and that seems to work okay. I've done this in a
number of problems, but this in an extreme case.
Attached are the codes with (LiquidProperties(Prints).txt) and without
(LiquidProperties(NoPrint).txt) the <web></web> tags.

Hi Robley,
I'm forwarding this to you in case you happen to skip over this. Could you
please respond to the list and/or Jay if you don't mind.

Tables should just print properly without having to do something
special. However, the table in this problem isn't a normal data table.
You are putting problem parts in table cells. Robley Light had a
similar problem and we resolved it be just wrapping the code for the
<table> tags inside of <web></web> tags. This way, the table just
appears on the web but prints with no table formatting. Robley, do you
remember where this problem is? Jay may find it helpful to look at it
and print it out and see if he likes this workaround.
