Tables are not very widely adopted by AutoCAD users but your standard needs to address them.
They include text objects – so I include this discussion here…
Are you going to use them?
Do you develop standard Tables?
Can users create their own?
Define the items that need input or save them as a Table Style. Go through the General, Text and Border tabs and define what your standards will be.
Here are some tutorials collect by CADDigest from the net.
