did you loook at the source code to see how they did it ?
mixed media content is usually achieved with some creative use of css in html tags.
for instance the following code will wrap text around a span of content ...
<p><span style="float:left"><!-- ad code here --></span>a poopload of text here</p>
will produce a left justified ad with text wrapping around.
change float to right for a right-justified ad.
works the same for images too and other blocks of content embeded.
ps- get away from anything table related unless you are displaying tabular data.
