probls with styles inside textarea

Hi Group...
I have a css file with an entry tablemain and some restrictions to border..

in HTML code, inside the textarea, i have a table also with borders, but they wont displayed..
here my code:
CSS:
table.tableMain{margin:10 0 10 0;width:100%;background-color:#EDEDED;border-color:000000;border-style:solid;border-left-width:0px;border-right-width:0px;border-top-width:1px;border-bottom-width:1px;font-size:12px;border-collapse:collapse;}
table.tableMain td{border-style:solid;border-width:0px; font-size:12px;border-color: #392c23;border-collapse:collapse;}


HTML:
<table class="tableMain" cellpadding="2" cellspacing="0" width="98%">
<tr>
<td class="head" valign="top">DESCRIPTION:</td>
<td>
// Begin Editor Content
<H2>General Terms of ....</H2>
