Dynamic elements above FixedHeader revisited

Dynamic elements above FixedHeader revisited

I was having the same problem as described in this thread:


I set up my table filter so that it would dynamically show/hide when an icon was clicked, which caused the cloned table headers to get out of sync with the real one. I found a (seemingly) simple way to fix this is to add a line in _fnScrollFixedHeader that hides the cloned header when it's above the table as such:

this._fnUpdateCache( oCache, 'sDisplay', "none", 'display', nTable.style );

And when below or middle, just do the opposite:

this._fnUpdateCache( oCache, 'sDisplay', "block", 'display', nTable.style );

It seems to work pretty well without the need to update for each iteration of a step function as discussed.

Somewhat related, I also found it helpful to call _fnUpdateClones in the scroll event listeners. The particular scenario involved two tables on a single page. When one was update via AJAX a scrollbar appeared on the page causing the cloned header width to not be correct on the other table,. Maybe there is a better way to handle this?

    Hey NolanCaster,

    I have also been trying to fix this issue. I attemped your method but it seemed to break the fixed header. Could you provide an example of the fix on jsbin or jsfiddle? Thanks in advance, this is killing me!

    My solution is based on Fixed Header.js v2.0.6. There were some changes in the 2.1.0wip that keep it from working quite right in that version.

    I had to paste my whole FixedHeader.js file into the jsbin to get it to work, but the result is here: http://live.datatables.net/ocikoq/edit#javascript,html

    If you click "Click Me" it should animate a div above the table, but without exposing duplicate header rows. The additions in question are in the function _fnScrollFixedHeader. I also added some analogous lines in _fnScrollFixedFooter.
