Hi,
The problem I am facing looks simple:

A table with few rows of data inside <div> (with id) and few more <div> tags to help scroll happen without hiding header. The scroll works fine normally when we use mousescroll or use scrollbar. Also the row is highlighted when is mouse over it. This is where problem is: When row is highlighted it puts off the scroll somehow and we cannot use mouse-scroll to scroll over table data. The table seems somehow locked for scroll.

The complete code is here:

var XtableEmulator = document.getElementById('x-table-emulator');
var table = document.getElementById('table-body');

YtableEmulator.style.height = table.clientHeight == 0 ? "330px" : table.clientHeight + "px";

var scrollablePanel = document.getElementById('scroll');
var headerContainer = document.getElementById('header-container');

YfakeScrollablePanel.style.top = headerContainer.clientHeight == 0 ? "34px" : headerContainer.clientHeight + "px";
scrollablePanel.onscroll = function (e) {
XfakeScrollablePanel.scrollTop = scrollablePanel.scrollTop;
}
YfakeScrollablePanel.onscroll = function (e) {

scrollablePanel.scrollLeft = XfakeScrollablePanel.scrollLeft;
headerContainer.scrollLeft = XfakeScrollablePanel.scrollLeft;
footerContainer.scrollLeft = XfakeScrollablePanel.scrollLeft;
}
</script>

</body>
</html>


The above code is complete and can be put in a fresh html file to see the table. Let me know if something not clear.

Please provide your suggestions..

Thanks in advance,
