Colgroup in Chrome

I am trying to line up a table, and it displays as expected in Firefox but not in Chrome.  All three columns are bumped up against each other.

HTML:

<div id='JKL'>
	<table class="warning">
		<tr>
			<colgroup>
			<col class="col1" />
			<col class="col2" />
			<col class="col3" />
			</colgroup>
			<td><img src="../images/arrowdown.gif"></td>
			<td>Don't stop here!<br><span class="secondline">Now</span></td>
			<td><img src="../images/arrowdown.gif"></td>
		</tr>
	</table>
</div>

Select allOpen in new window

CSS:

#JKL .warning table
{
    background: #ffffff;
    overflow: hidden;
    margin-bottom: 20px;
    margin-top: 20px;
	margin-left:auto;
	margin-right:auto;
	height: 30px;
}
#JKL .warning td
{
    font-size: 16px;
	font-weight:bold;
	padding-top: 10px;
	margin-left:auto;
	margin-right:auto;
	text-align: center;
	vertical-align: center;
}
#JKL .warning .col1 .col3
{
    width: 60px;
}
#JKL .warning .col2
{
    width: 90%;
}

#JKL .warning td .secondline
{
    font-size: 12px;
	padding: 5px;
	margin-left: 2px;
	vertical-align:top;
	height: 30px;
}
