So you can't set border properties on a row. The important CSS here is:
table {
border-collapse: collapse; /* this is pretty straight forward
but it collapses each of the individual
cell borders into each other */
border: 1px solid black; /* this puts the border around the whole table */
}
td {
border-bottom: 1px solid black; /* this puts the bottom border on each row */
padding: 10px; /* this could be set to anything but gives your table a little spacing. */
}
I hope this helps. See http://jsfiddle.net/RF5jC/ for demo.
