Maybe I misunderstood. Is your data source your site? If so, ignore my observations about TOS; if not, I repeat, "beware!"
The balance of your first graf suggests that stockta.com is the IP of some other entity, but if that entity approves of you using their data, they likely have a published API. Ask. And if they don't approve? Well refer to para 1.
How did using <c><table width="34%" border="1">
<tr>
<td>aaa</td><td>bbb ccc ddd></td><td>2012-12-04</td><td>foo</td><tr>
...</table> -- ie, html here</c>
fail? Note that the closing tag is -- as is customary (or, as here, required) </c> ... with a slash!
Even raw html renders so long as it's of a reasonable width (and within the limits allowed by the fact that PM's html is restricted):
a a a | ab bb | 2012-12-04 | foo |
12345 | 0987654321zyx | 20121204 16:49 | bar |
