wordpress table design question

[Chuck Rowan]

I am having a couple questions regarding WordPress tables. I can't get the table to center on the page and to also remove the lines around the table. Here's a copy of the code:

<table align="center" border="0" cellpadding="0" cellspacing="1" style="width: 500px;">
<tbody>
<tr>
<td>
<a href="http://www.army.mil/" rel="" style="" target="_blank" title=""><img alt="U.S. Department of the Army" class="aligncenter size-full wp-image-1000" height="1000" src="http://www.ncgeeks.org/wp-content/uploads/2015/03/U.S.-Department-of-the-Army-DA-Seal1.5.png" style="border: 0px; margin: 0px;" title="US Army" width="1000" /></a>
</td>
<td>
<a href="http://www.navy.mil/" rel="" style="" target="_blank" title=""><img alt="US Navy" class="aligncenter size-full wp-image-1000" height="1000" src="http://www.ncgeeks.org/wp-content/uploads/2015/03/US-Navy-USN-Emblem1.5.png" style="border: 0px; margin-top: 0px; margin-bottom: 0px;" title="US Navy" width="1000" /></a>
</td>
<td>
<a href="http://www.usmc.mil" rel="" style="" target="_blank" title=""><img alt="US Marine Corps" class="aligncenter size-full wp-image-1000" height="1000" src="http://www.ncgeeks.org/wp-content/uploads/2015/03/US-Marine-Corps-Seal-2x2-150x150.png" style="border: 0px; margin: 0px;" title="US Marine Corps" width="1000" /></a>
