I have an html table within a div of a specific size. I want the table to apply margin collapse and be 100% wide. Here is my code. It renders how I want it to in IE8 and incorrectly in Firefox. Firefox may be doing the spec correctly, but whatever. How do I fix my css to work in both browsers?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
<html xmlns="http://www.w3.org/1999/xhtml"&gt;

<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>Untitled 1</title>

<style type="text/css">
table
{
    border-collapse: collapse;
    border-spacing: 0;
}

table
{
    margin: 10px 0;
    width: 100%;
    display: block;
}

p
{
    margin: 10px 0;
}

td, th
{
    border: 1px solid #000000;
}

</style>
</head>

<body>

<div style="width: 600px; border: 1px purple solid;">

<p>Some text at the top.  Notice that the margin collapse does not work unless display:block.</p>

<table>
    <tr>
        <th></th>
        <th>Header 1</th>
        <th>Header 2</th>
        <th>Header 3</th>
    </tr>
    <tr>
        <td>Label 1</td>
        <td>1.A</td>
        <td>1.B</td>
        <td>1.c</td>
    </tr>
    <tr>
        <td>Label 2</td>
        <td>2.A</td>
        <td>2.B</td>
        <td>2.c</td>
    </tr>
</table>

<p>Some text at the bottom.  Notice that the margin collapse does not work unless display:block.  Its stupid.</p>


</div>

</body>

</html>

I need the display:block for margin collapsing to work in Firefox. If you remove the display:block, you should notice that the spacing between the <p> tags widens from 10px to 20px.

This is also an edit to this question that I posted earlier, but it won't let me edit for some reason. I've been messing around with my internet cache so I probably messed up a cookie.

Margin collapse doesn't work in firefox. The margin to the top and bottom of table adds with the p instead of collapsing to 10px.

@maggie Margin collapsing is only defined for block elements, i have update post check once again.

I want margin collapsing on the table, therefore I defined it as a block element. Should I be doing something else to achieve the same effect? I'm using display:block based on similar reasoning to this post: http://stackoverflow.com/questions/136727/why-doesnt-a-tables-margin-collapse-with-an-adjacent-p

@maggie "You could use a 1-pixel top padding or border to avoid margins from collapsing."

I want margins to collapse. As in if there is a `<p>` with a 10 px margin-bottom and a table next with a 10px margin-top, I only want there to be a 10px space, not 20px. Am i using the term margin collapsing write.

A: 

if removing display: block breaks in IE use '\9' to target IE only like:

table 
{ 
    margin: 10px 0; 
    width: 100%; 
    display: block\9; /*for ie only"*/

}

Thats a good tip to know. In this situation IE renders how I want it to look; whether that's how it should look based on the code, is another story I just don't care about.

You need to define the parent elements as 100% too, so the table knows what it is a percentage of.
