Unfortunately there is no built in method to do that 'diff' in DataTables at the moment. A reload, as you say will destroy all of the old rows and replace with new. A plug-in method could be created that will make the Ajax request and then use row.add(), row().data() and row().remove() as required,but it is not something that I currently have. If you create one, I'm sure others would be interested if you could share it (I know I would :-) ). Allan

Thanks for your kind response Allan. and please help me to solve one issue, which is i'm facing, from the following link https://datatables.net/forums/discussion/30787/how-to-use-drawcallback-for-particular-column-only

Thanks Allan, but i went as per below documentation, as length, search, info, pagination all are visible but not buttons, "dom - DataTables' DOM control parameter - this option is only available if you also use buttons. Additionally, if you use anything other than the DataTables default styling, you probably don't want to use this option!" So i am using bootstrap styling, so i still need to use dom? Thanks Allan,

Thank you @jLinux for reply... It seems that this is the answer what I was expecting... Let I'll go through the links

Thanks. Resolved.

Use the "Buttons" extension. http://datatables.net/extensions/buttons/

There is no option to set that parameter after initialisation I'm afraid. You would need to make the Ajax call yourself and then use clear() and rows.add() to clear existing rows and add the new data (which is basically what ajax.reload() does itself). Allan

Thanks Allan, you're the best. I needed to change all objects in the array, I ended up using: table.rows().remove().rows.add(data).draw();
