print table without internal borders

If I understand the question, 'properties' will not eliminate these
lines because they were added when the table was built;
           to eliminate them, you'll need to eliminate all the exterior
tables, leaving only the innermost table.

       Open the document to show all then you should see where the table
was set ... another was set ... etc. etc. etc. ...
           then the data was added;
         eliminate the extraneous one(s) - making sure to eliminate the
opening and closing to each not desired.

       Hoping this helps,
