How to vertically scroll 2-col-Tables per DHTML? [Archive]

Hey, I found this piece of code on the net:

http://www.dyn-web.com/dhtml/scroll/

especially http://www.dyn-web.com/dhtml/scroll/glide-scroll-rel-v.html

Well, this one scrolls a table, but

1.) views only one element at a time
2.) scrolls only one column
3.) only images !

Is it possible to change that? What I want to accomplish essentially is vertically scrolling a table, that will become longer/higher as content is added, but I don't want to use browser-scrollbars. Instead of those, I'd rather those buttons. What to do?

This is an unclear statement. If you're employing a scroll, the table's dimensions should remain static. :confused:
So, are you wanting the area's dimensions to be static or dynamic?

Static of course. I just implied that the "area" might grow in size with time, but as it's a static document, that shouldn't be a problem.

Someone had a similar request recently. I can't find the post, now. But here's an example:

<style type="text/css">
#divUpControl{
position:absolute;
width:66px;
left:510px;
top:40px;
z-index:1;
text-align: right;
height: 19px;
}
#divDownControl{
position:absolute;
width:82px;
left:500px;
top:233px;
z-index:1;
text-align: right;
height: 19px;
}
#divContainer{position:absolute; width:502px; height:240px; overflow:hidden; top:30; left:10; clip:rect(0 505 240 0); visibility:visible}
#divContent{position:absolute; top:0; left:0}
</style>
