Either way, the question is too ambiguous, without
any explanation of what is seen or not seen and specifics
as to what is wanted.
There was another question on gridlines elsewhere that was
not covered on my gridline.htm page that I had not considered,
the complaint was that the gridlines did not cover the entire
worksheet just down to the last used cell (Ctrl+End). There were
two solutions one was to put a barely noticeable period down lower.
The other was to expand the print area. Both work. I'd tend to
shy away from things that may not show all data, or print extra (blank) pages
if you insert more rows/columns. The print area is temporary though.
