Modifying columns after ajax, before show

dacesilian

What is the best way how to modify row column content, e.g. add a button?
Now I am doing it with:

"fnRowCallback" : function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
$('td:eq(0)', nRow).html(...
$('td:eq(1)', nRow).html(...

DataTables load is very slow when I use this way. Is there any better way?

I want to be able to add some buttons, input and so on.

I'm using "bProcessing" : true, "bDeferRender" : true.

Thank you
