For Emebed/Nested Table (table in table):

What you _can_ do is to formulate your CSS rules so that they apply to
the desired elements only. For example, to make some rule apply only to
td elements in a table that is nested inside another table, you can
write
table table td { ... }

You _cannot_ formulate CSS rules so that they apply only to, say, cells
of a table that is _not_ nested inside another table. But you can
specify a rule that applies to all cells, and then _override_ it with a
rule that applies to some cells only. For example:
td { border: solid red thin; }
table table td { border: none; }

For Tr to disappear:

display:'block' won't work;

just use  display:'' for TR
