Could be you're seeing the leftovers from a partially deleted drawing
object, etc........try moving the cursor slowly over the "border" and if it
changes shape, Right-click and CUT..........you may have to do this several
times............

In my sheet, I have a bunch of cells that have dotted borders,
I cannot change this under format.
When I add a column alongside, that part of the column offers no
gridlines at all, all is blank.

How do I rectify this please, and get back to naormal cell border format?

Thank you.
