Firefox 1 pixel bug with border-collapse, workaround?

Is there any workaround for the following "1 pixel to the left" bug?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<body>
<div style="padding: 50px">
<div style="border: 1px solid red">Table header info</div>
<table style="border: 1px solid green; border-collapse: collapse; width: 100%">
<tbody>
<tr>
<th>Col1</th>
<th>Col2</th>
</tr>
<tr>
<td>Hello</td>
<td>World</td>
</tr>
</tbody>
</table>
<div style="border: 1px solid red">Table footer info</div>
</div>
</body>
</html>


It looks like this:

Is there any pure CSS solution to this?




Edit



I was bit unclear about my table so here it is again:

With border-collapse:

With cellspacing="0" and without border-collapse as suggested:

So now the borders inside my table are doubled, but I want 1px border across my table.

When I remove 1px border from table I end with:

Firefox CSS bug

Borders are still doubled inside my table.

I could set only right and bottom border for every TD, TH and left border for every first-child in TR to achieve what I want, but I think there's a simpler way?

BTW it's a known bug since 7 years, it'll be probably fixed in version 3.6 duh! Test case is avalible here (taken from bugzilla discussion).

Answer

Remove the border-collapse and use cellspacing=0 instead.

<table style="border: 15px solid green; width: 100%"  cellspacing="0">

It happens because when you set border-collapse:collapse, Firefox 2.0 puts the border to the outside of the tr. The other browsers put it on the inside.

Set your border widths to 10px in your code to see what is really happening.


edit after OP edit

You can use the old table "border" trick. Set the background color on the table. Set the td and th color to white. User cellspacing = 1;

table {background-color: green;width:100%;}
td, th{background-color:white;}

<div style="padding: 50px">
<div style="border: 1px solid red">Table header info</div>
<table cellspacing="1" >
        <tbody>
                <tr>
                        <th>Col1</th>
                        <th>Col2</th>
                </tr>
                <tr>
                        <td>Hello</td>
                        <td>World</td>
                </tr>
        </tbody>
</table>
<div style="border: 1px solid red">Table footer info</div>
</div>
