this is a table with a frame inside :
QUOTE
<table width="100%" border="0">
<tr>
<td>
<iframe src="http://www.zymic.com" name="myframename" frameborder="0" width="700" height="700"></iframe>
</td>
</tr>
</table>
So lets explain :
the table width is 100% wich means it will go as big as the content inside or as big as the screen. since i have set my iframe to 700 by 700 the table will be that large.
there is NO border for this table since i have set it at 0
the iframe will have www.zymic.com inside so inside the 700 700 box you will see the zymic website

(wich as you can gues is kinda small, i think it uses a width of 950 anyways....
for the frameborder you re probably asking what it is, i have found that sometimes iframes have a border, i tryed seting the border to 0 inside the iframe tag but never worked... and at some place i have found a iframeborder, i set it and the borders disapeared

also i named the iframe. why ? well sometimes you have more than 1 iframe inside your site since you set a location you need to set a name. lets say
QUOTE
<a href="blablza.html" target="myframenumberone">HERE</a>
once you clic HERE the blablza.html will apear on the frame called myframenumberone
this is an iframe inside a border.not sure if its what you were asking by :
