I am “moving” 28 pages that was written in HTML over to WordPress.  Everything was written using tables.  I have copied the “code” over and it seems to be working, but there are lines between the rows and the tables that wasn’t there before.  For example:
http://www.larryg.com/mdwsa2/2009/06/12/2009-spring-fling-golf-extravaganza/   (WordPress site)
http://www.mdwsa.org/php/mdwsaorg.php?topic=2009SpringFlingGolf   Prior site using HTML only.
I see in the appearance, editor the table format of:
table,
table caption {
  border: 1px solid rgba(0, 0, 0, 0.25);
  border-width: 1px 1px 0 1px;
}
table {
  border-collapse: collapse;
  font-size: 16px;
  font-size: 1rem;
  line-height: 1.2;
  margin: 0 0 28px;
  table-layout: fixed;
  /* Prevents HTML tables from becoming too wide */
  width: 100%;
}
table caption {
  text-align: center;
}
table a {
  color: rgba(0, 0, 0, 0.70);
  font-weight: 700;
}
th {
  text-align: left;
}
th,
td,
table caption {
  padding: 21px;
}
tr {
  border-bottom: 1px solid rgba(0, 0, 0, 0.12);
}
I believe I need to change border: 1px to 0px.  BUT, I really don’t want to do this within the editor.  Not sure if I can do something in the “additional CSS” like you had me do before and if so what or if I need/should do something on each of the 28 pages that I am moving over and if so what.
Thanks
