I've been tearing my hair out on this one. Whether I try to implement column re-ordering via header dragging or via the column chooser plugin, after re-ordering the columns, clicking on any column header to sort results in the sorted columns being loaded into their original positions in the table. I've tried the suggestions posted here but nothing seems to work. Using the sortable method:

sortable: {

options: {

stop: function(event, ui){

// have tried putting the remapcolumns function inside stop() to no avail
