We have not changed the table’s default behavior. The sorting of table header is the default behavior supported by Java. In fact, most tables do not support turning off sorting by clicking header the 3rd time. A common example is tables in Windows’s explorer.
So is there no way to recover my previous sort? How it was sorted previous to me clicking the column. It seems to me the arrows that move the requirements up and down are pointless. As soon as you click a column, even by accident, it’s tough luck.
