Colreorder slow on IE and Chrome

Raghavan

We are trying to use ColReorder on a DataTable, How to improve colreorder performance that has more than 200 rows and 50 columns. Please need a support on this
Tried using the following line:

gridSettings.colReorder = {
"fixedColumnsLeft": fixColIdx
};

I facing an issue on colreorder slowness in datatable API (datatables.colreorder.js)/

there is drag (Mousemove) and drop (Mouseup) the columns with iteration of datatable total no of columns from below mousemove and mouseup.

File: Datatable API (datatables.colreorder.js)

$(document)
.on( 'mousemove.ColReorder', function (e) {
that._fnMouseMove.call( that, e );
} )
.on( 'mouseup.ColReorder', function (e) {
that._fnMouseUp.call( that, e );
} );

You could try using colReorder.realtime to disable the update while dragging.

Aside from that, please link to a test case showing the issue, per the forum rules, so it can be analysed and debugged.
