Cell border on just one side

Hello,
Trying to make it so borders on my cells in a table show up on one side and that’s it.

Can’t figure it out for the life of me!

My page is here: https://blacktop.cornick.us/?page_id=79
I’d like a ‘column’ border shooting down separating the columns so you can easily figure out what is what.

A quick snipit of code that is used but doesn’t seem to show up, not sure why.

<tr bgcolor="BBBBBB">
<td align="left"><span style="font-family: Arial; color: #000000;">Best Record</span></td>
<td border-left-width:2px><align="center"><span style="font-family: Arial; color: #000000;">12-1</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">Magil</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">2005</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">11-2</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">Prisk</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">2006</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">11-2</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">Prisk</span></td>
<td align="center"><span style="font-family: Arial; color: #000000;">2003</span></td>
</tr>

Any ideas? Thanks!
