Remove Space Above Table

I have made a table on this page here.

It takes a while to load as there are server issues.

There’s an inch of space between the table and the header above it I want to remove. I don’t see what’s causing this as there’s nothing in the code to create space that I see of so that tells me there’s some css parameter I want to change.

Here’s the code I’m using to create the page:

If you plan to attend the Literacy Student & Alumni Reunion please register for this?separately below.<hr>

<table class="certain2" border="0">
<th colspan="2"><strong>Literacy Conference Registration</strong></th>
<tr>
<td style="vertical-align:middle;"><form action="/index.php/events/claris-50th-anniversary/clari-literacy-conference/conference-registration/literacy-conference-registratio/"><input type="submit" value="Register Now!" /></form></td>
<td style="vertical-align:middle;">Saturday, June 29th, 2013 - Literacy Conference, from 8:00 - 4:30 p.m.</span>
Keynote speaker: Taffy Raphael (University of Illinois, Chicago)
</td>
</tr>

<th colspan="2"><strong>2013 UB Literacy Student & Alumni Reunion Registration</strong></th>
<tr>
<td style="vertical-align:middle;"><form action="/index.php/events/claris-50th-anniversary/clari-literacy-conference/conference-registration/student-alumni-reunion/"><input type="submit" value="Register Now!" /></form></td>
<td style="vertical-align:middle;">Friday, June 28th, 2013 - UB Literacy/Reading Reunion, from 5:30 - 7:00 p.m.</span>
Socialize with old friends, network, find out what is happening at CLaRI</td>
</tr>
</table>

And I have modified the table using the following in the style.css

/*changes table font size of the class certain*/
table.certain2{
	font-size:13px;
    margin: 0px;
    border-collapse: collapse;
    padding: 0px;
}

I’m using the twenty twelve theme (with a child)

Thank you in advance.
