CSS Table width not being able to be set - css

Question

2 Columns, a few rows.
The width of the entire table seems to be set for good. No chance of changing it. All I can do is move the row separator so one columns gets stretched while the other expands.
This is the CSS file.
body {
font: normal 11px auto "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
color: #4f6b72;
background: #E6EAE9;
}
a {
color: #c75f3e;
}
#mytable {
width: 450px;
padding: 0;
margin: 0;
height: 39px;
}
caption {
padding: 0 0 5px 0;
width: 489px;
font: italic 11px "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
text-align: right;
}
th {
font: bold 11px "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
color: #4f6b72;
border-right: 1px solid #C1DAD7;
border-bottom: 1px solid #C1DAD7;
border-top: 1px solid #C1DAD7;
letter-spacing: 2px;
text-transform: uppercase;
text-align: left;
padding: 6px 6px 6px 12px;
background: #CAE8EA url(images/bg_header.jpg) no-repeat;
}
th.nobg {
border-top: 0;
border-left: 0;
border-right: 1px solid #C1DAD7;
background: none;
}
td {
border-right: 1px solid #C1DAD7;
border-bottom: 1px solid #C1DAD7;
background: #fff;
padding: 6px 6px 6px 12px;
color: #4f6b72;
}
td.alt {
background: #F5FAFA;
color: #797268;
}
th.spec {
border-left: 1px solid #C1DAD7;
border-top: 0;
background: #fff url(images/bullet1.gif) no-repeat;;
font: bold 10px "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
}
th.specalt {
border-left: 1px solid #C1DAD7;
border-top: 0;
background: #f5fafa url(images/bullet2.gif) no-repeat;;
font: bold 10px "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
color: #797268;
}
And this the table.
<table id="mytable" cellspacing ="0">
<caption>Table 1: Descriptions </caption>
<tr>
<th scope="col" abbr="Configurations" class="nobg" style="width: 47px">Configurations</th>
<th scope="col" abbr="Dual 1.8GHz">Original Stack</th>
</tr>
<tr>
<th scope="row" class="spec" style="width: 47px">Model</th>
<td class="style1">3xPa</td>
</tr>
<tr>
<th scope="row" class="specalt" style="width: 47px">Year</th>
<td class="alt" style="width: 181px">1998/A</td>
</tr>
</table>
I'm not sure what's preventing me from changing the width of the entire table. I've tried changing the width property in #mytable but it's doing absolutely nothing. I'm using VS 2010, aspx webform.
Any idea?

Changing the table width in the css works fine for me on chrome.
Try removing the width for your caption, the absolute width on the caption might be tricking you into thinking the table size is not changing...
caption {
padding: 0 0 5px 0;
/*width: 489px; Commented Out */
font: italic 11px "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
text-align: right;
}
