removing table border

Try giving your table an ID and then using !important to set border to none in CSS. If JavaScript is tampering with your table then that should get around it.

<table id="mytable"
...

table#mytable,
table#mytable td
{
    border: none !important;
}

Please try to add this into inside the table tag.

border="0" cellspacing="0" cellpadding="0"

<table  border="0" cellspacing="0" cellpadding="0">
...
</table>
