I'm looking at it in FF and it looks OK to me. I can't find anything in your style sheet that's called for in the html and doesn't appear.
I think you are asking for trouble by mixing inline styles and depreciated html as well as the style sheet (which you are hardly using). I would suggest moving everything on to your style sheet and not using html for formatting. You can replace the inline styles used on your <td>'s by classes in your style sheet eg instead of
<TD style="border-bottom-style: solid; border-bottom-width: 1px; border-left-style:solid; border-left-width:1px; border-right-style:solid; border-right-width:1px" bordercolor="#EC6909" bordercolorlight="#EC6909" bordercolordark="#EC6909">
Put this in your css
.cell1{border: 1px solid #EC6909;}
And call the class in your table cells when required like this
<td class="cell1">Cell content here</td>
