(conditional cell formatting) add class to cell (td) from within render function

xtech_dev

I would like to achieve conditional formatting based on cell value. Is it possible to add class to td element from inside of render function?

I have tried but it seems to not have any effect.

function (data, type, row, meta) {
   if (type == "display") {
      var $table = $(meta.settings.oInstance.api().table().node());
      var $td = $table.find('tr:eq(' + meta.row + ') > td:eq(' + meta.col + ')');
       $td.addClass('bkg-red');
   }
}

I have seen solution with rowCallback option (https://datatables.net/forums/discussion/comment/110916/#Comment_110916) but i would prefer to keep render logic in "one place".

Any ideas?

My understanding is columns.render is meant to manipulate the data in the table and is not meant for manipulating the HTML. So there are no provisions provided for HTML manipulation in columns.render.

createdRow and columns.createdCell are built for this functionality. And as you mentioned rowCallback can also be used.
