Why do rows in a table stack when adding a new row?

[Dottie in Asheville NC]

I have made a table that goes to 4 pages. To add rows, I've just hit TAB and
this has worked fine. Now, on page four, when I add a row, previous rows
stack on top of each other. What am I doing wrong? I tried to go to
Table-Add row, and that doesn't make any difference. It still stacks
previous rows.

What exactly do you mean by "stack on top of each other"?

What is typed in one row goes up to the previous row and prints on top of
what is there.
