HTML TD width not taking effect - html

Question

I've got two TD's at the bottom left of my HTML email layout, but the first is not taking effect of the 140px width I've set, any obvious reason why?

<td class="blue-table" width="375px" valign="top">
<table class="blue-table" cellspacing="0" cellpadding="0">
<tr>
<td>

</tr>
<tr>
<td class="blue-table" width="20px"></td>

Answer 1

Looks like you've got two cells in your final row - and only one cell in each row above that. This means your table is effectively two columns wide, with the picture of the car in a tacked-on column by itself. This will be messing up the width calculations.
One way to handle this is to make the one-cell rows span two columns each, and leave the two-cell row as is. colspan will do this, and it is applied something like this:
<tr>
<td colspan="2">

You need to do this to every row.
This should give your width settings more predictable results.
You can double-check your table layout by giving your table cells a temporary border with CSS like this:
td {
border: 1px solid red;
}
Edit
Potentially a better solution would be to use CSS, and float: right the picture of the car (add a margin or padding to put some space around it). Then you can treat everything inside <td class="blue-table" width="375px" valign="top"> like a normal set of paragraphs and images and avoid colspan altogether. There is a long post about the merits or otherwise of using tables for layout here if you're interested: Why not use tables for layout in HTML?

Answer 2

Try this:
<td width="140">
or
<td style="width: 140px">
