plugin doesn't work when table is in a bootstrap3/jqueryui tab
after version 1.2.12, this plugin should work within bootstrap3/jqueryui tabs by listening to tab change events. Make an issue if its still busted.
The scrolling container has absolute position with top:0;left:0;right:0;bottom:0 css
init plugin with position:'fixed' and see this example solution: issue 205
scroll container is not working (header does not float)
scroll container should be the closest parent of table with position:relative;overflow:auto;height:n px;. If it is not, things wont work.
The scroll container must be the container that scrolls both the x and y axis. It also helps if the container is as close to the table as possible (in terms of number of element between the scroll container and table)
IE ONLY: header noticeably skips/jumps as you scroll
I did a bit of IE researching and found that by unchecking IE's "Use smooth scrolling" setting, this issue no longer exists. You can do this by clicking the settings cog/gear -> Internet Options -> Advanced (tab) -> Browsing -> "Use smooth scrolling" (uncheck).
see issue #233
