Scrolling with CSS - css

Question

I have 4 tables that need to scroll, they are set up as follows:
Table1(static)
Table2(Horizontal Scrolling)
Table3(Vertical Scrolling)
Table4(Horizontal and Vertical Scrolling)
Table1 Table2
Table3 Table4
The tricky part of this is that Table 3 and 4 need to keep in sync as this is a listing of data broken out into two tables. Table 2 and 4 are in the same situation.
Any ideas?
No Javascript please as we have a script that works, but it is far too slow to work.
Thanks.

We got the code from this link.
I hope this helps.
As it stands, the code is far too bulky to process the amount of data we need to. We have approximately 5000 rows of data per month that needs to be displayed on the page.

Answer 1

If by "need to keep in sync" you mean that when you scroll one of them, the other scrolls too, you can't do this with CSS, because you can't manipulate scroll position using CSS.
And one more thing, have in mind that scrollbar in IE goes inside the element and overlaps 20px of this element (there is a workaround for this), and in all other browsers scrollbar goes outside the element.

Answer 2

You can use CSS to set the height of an element and then set overflow:auto (this will give you scroll bars when needed).
Its very hard to get rows of a table to scroll properly. I've been trying with things such as wrapping a table row in a div (or vice versa) and setting a max-height and overflow of that div.
That's the best I can do with out seeing what you are trying to do.

I appoligize, this part will not format no matter what I do, sorry about the poor formatting.
