container width?

[swift2013]

I have a paragraph which has width=200px and is contained in a div.
The div is placed within the table cell, which has width=50px
In IE6, Firefox 2.0.0.6 the div has offsetWidth of 200px,
but ie7 renders it with 50px.

How can i force ie7 to set div's width by its contents?

<style>
table.narrowTab le tr td {
width: 50px;
}
p.wideParagraph {
width: 200px;
}
</style>

<table class="narrowTa ble">
<tr>
<td>
<div id='container'>
<p class="widePara graph">This paragraph </p>
</div>
</td>
</tr>
</table>
