No thats not a good method, that is not what you want to do. That causes problems in that you can only put text inside of it not images or other elements. Also it looks like crap. There are two good ways to do it. A use a div with overflow specified as scroll or auto. To do this put this inside the cell
<div style="height:yourheight;width:yourwidth;overflow:auto;">stuff in the div</div>
the other way to do it is by using an iframe. An iframe is a frame though so you will need another html file to open inside of it.
<iframe src="thepageinside" name="iframename" height="someheight" width="somewidth"><a href="thepageinside">You dont support an iframe</a></iframe> The upside of the iframe is you can have links open inside of it by using <a href="somepage" target="iframename">link</a>
To see it done with an iframe view my site www.clanknights.vze.com, to play around with different overflows for a div go to http://www.w3schools.com/css/tryit.a...rycss_overflow
I simplified the only too practical methods to do this, so if you have problems refer to my post above. There is a thrid way to do it, which is using an ilayer but that is a bunch of code and it is not very well supported.
