I get, from time to time, vertical lines in table columns. In one case now, the line is 1/2 inch from the left table border, and goes down, breaks up, and then continues an inch later and continues to the bottom of the table. These lines can occur in other pages too, in the same table.
I can usually get rid of them by doing I don't know what, but now, I am stuck, in spite of saving and opening the file again.
I do not know what these vertical lies are, how/why they appear. Any help would be appreciated.
Thanks,
Hans L
