Excellent, you're really getting there! FF works perfect, and I notice no lag or delay at all.
IE7 and IE6 work perfect for the header-row, but the left fixed column has some problems: - the actual table rows seem to be slightly shorter in height than the fixed column rows. This causes a gradually growing misalignment between the content of the fixed column and the actual data on normal columns. - the last entry/row in the fixed column gets hidden and is only partially visible. This is propably linked to the previous bug. Opera works perfect for the header row, but the fixed column has serious problems, gets improperly aligned to the top. All in All you have already done an amazing job. I've dug the net looking for a way to easily or even difficultly creating a scrollable table with a fixed header row that would work in all major browsers. I know others have too, yet there are none. You've already accomplished this and made it dead-easy with no need to hassle with extra DOM- elements and so forth. And all of it in a jQuery plugin, what more could we wish for! You're bound to also invite lots of new people to jQuery once you get this thing public. Currently there is no other easy way to get this functionality, AFAIK, so people will come :) The fixed columns is a bonus and I hope you get that working too.
