I cannot make the borders in a Numbers table stay in the table nor print?

Frustrated,

Jim.....

Thanks Michael for the vidio.

I neglected to tell you that I did select the entire table, then apply the "Inside Borders" selection and the borders appeared. I also selected "Apply Border Selection" from the "Borders" menu. Then if I click anywhere within the table or outside of the table the borders disappear. Also after applying the borders and then going to print the borders do not print. I even went so far to reload the Numbers application from disc.
