Want to make entire TD cell an anchor

Question

I have a <table> where each <td> holds only an anchor. I'd like users to be able to click anywhere in the cell to visit that reference rather than only on the anchor text itself. I imagine there must be a bit of jQuery to do this easily. Can anyone help?

Edit: To complicate things, my td's have some top and bottom padding. A display: block; rule doesn't seem to work in this case. I've edited the example:

CSS:

table#mainmenu td {
    padding: 9px 8px 5px;
    border: none;
    border-bottom: 1px solid #ccc;
    border-left: 1px dotted; 
    text-align: left;
}

Example:

<table>
<tr>
  <td><a href="foo.html">Foo</a></td>
  <td><a href="bar.html">Bar</a></td>
</tr>
<tr>
  <td><a href="foobar.html">FooBar</a></td>
  <td><a href="barfoo.html">BarFoo</a></td>
</tr>
</table>

Answer 1

Just make the A tag display: block.

table td a {
  display: block;
}

Or, if you insist on jQuery:

$('table td a').css('display','block');

EDIT

Since I wasn't able to find a CSS-only way to select a parent TD of a child A, this solution does use jQuery:

function doTablePadding() {
    $td = $('table td');
    $td.has('a').css('padding','0');
    padding = $td.not(':has(a)').css('padding-top') + " ";
    padding += $td.not(':has(a)').css('padding-right') + " ";
    padding += $td.not(':has(a)').css('padding-bottom') + " ";
    padding += $td.not(':has(a)').css('padding-left') + " ";
    $td.children('a').css('padding',padding);
}
doTablePadding();
$('table tbody').append("<tr><td>Stuff</td><td><p>Other stuff</p></td></tr>");
$('table tbody').append('<tr><td><a href="foo.html">Foo</a></td><td><a href="bar.html">Bar</a></td></tr>');
doTablePadding();

Note that this is running from $(document).ready();.

EDIT 2

As mu is too short notes, negative margins should work (and no jQuery):

td {
    padding: 5px;
    background: #0ff;
    border: 1px solid black;
}
td a {
    display: block;
    margin: -5px;
    padding: 5px;
    background: #f0f;
}

Answer 2

$(function(){
   $('td').click(function(){
    window.location = $("a", this).attr("href");
  });
})
