Backup old cursor and onclick

Change cursor and onclick

The event object is destroyed after this thread, but we are only need
The srcelement and/or the target

Call SortColumn in a new thread to allow the UI thread to be updated
With the Cursor/onclick
Window.settimeout (function () {

Once done resore cursor and onclick
Table.style.cursor = Oldcursor;

Get the index of the TD
