Learning things "table object"

[Bill]

I was complaining earlier about how table objects scroll automatically,
arbitrarily lock and unlock text, exhibit weird behavior with data in the
cells that is visible actually different than the data that is there. I
found out that all you do is unselect the check mark "table object" and then
all is fine. You have a nice field with a grid that behaves normally.

So what is a "table object" and why would anyone want it?
