Q:

 width returns 0 for IE and Chrome

I have a table with three columns. I am using  tag to specify the width of a column. Sample code:
<table width="100%" border="1">
  <colgroup style="background-color:#FF0000;">
  <col width="100px" id="id1"></col>
  <col width="80px" id="id2"></col><col id="id3"></col></colgroup>
  <tbody>
  <tr>
    <th>ISBN</th>
    <th>Title</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>3476896</td>
    <td>My first HTML</td>
    <td>$53</td>
  </tr>
  <tr>
    <td>2489604</td>
    <td>My first CSS</td>
    <td>$47</td>
  </tr>
<tbody>
</table>

The problem is width of col ($("#id1").width()) returns 0 for IE and Chrome and it works fine in FF.
How do I get the actual width of col in chrome and IE?

A:

Do the simple hack for older jQuery (col don't have width in Chrome, but it have first cell with width )
<table width="100%" border="1">
  <colgroup style="background-color:#FF0000;">
  <col width="100px"></col>
  <col width="80px"></col><col id="id3"></col></colgroup>
  <tbody>
  <tr>
    <th id="id1">ISBN</th>
    <th id="id2">Title</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>3476896</td>
    <td>My first HTML</td>
    <td>$53</td>
  </tr>
  <tr>
    <td>2489604</td>
    <td>My first CSS</td>
    <td>$47</td>
  </tr>
<tbody>
</table>
