My b2evolution Version: Not Entered

Using b2evolution 1.8.6

When I try to use this code...

<table border cellpadding=4>
<tr><th>Date</th><th>Probe</th><th>Nation</th><th>Result</th></tr>
<tr><td>February 4, 1961</td><td>Soviet Union</td><td>Sputnik 7</td><td>Direct Impact Trajectory, failed second stage.</td></tr>
</table>

I get the error message "Parser error: not well-formed (invalid token) near <table border cellpadding=4> <tr>"

I'm having a heck of a time getting this table to work. Any thoughts?
