I posted this same answer under you identical post for
Document mangagement. Good luck

DNC,

You can put your table between section breaks and protect
that section with a password.

Make sure only the table and text you don't want altered
is between these section breaks. Then, at the beginning of
the area you want protected use...

Insert | Break | Continuous: or next page if you want a
page break there, otherwise Continuous if you want on the
same page.

After you've inserted a break both before and after the
table, click....

Tools | Protect Document | Sections: and mark the section
you want protected. Include a password if you wish.
