thx Colin, I'll take a look...

We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here. Cheers, Colin

Use createdCell or createdRow. If the data can change then use rowCallback instead. Kevin

That is correct and expected. We do not currently copy across the classes that were added externally. If that is something you want to do you'd need to use either a custom renderer, or probably easier, use responsive-display to modify the display elements when the details information is shown. Allan

I just want to add to this to help someone in the future. The method I mentioned of not defining the non-editable fields in the editor instance is not the correct way to go about it. There is the readonly field type which should be used instead. And if necessary, you can use fields.submit to prevent the field from being passed for update. Example: editor = new $.fn.dataTable.Editor( { table: "#example", fields: [ { label: "Name:", name: "name" }, { label: "Position:", name: "position" }, { label: "Office:", name: "office" }, { label: "Age:", name: "age" }, { label: "Start date:", name: "start_date", type: "datetime" }, { label: "Salary:", name: "salary", type: 'readonly', submit: false /* Optional */ } ], formOptions: { main: { scope: 'cell' // Allow multi-row editing with cell selection } } } );

Use columns.render to perform the calculation.

There are lots of threads discussing this, like this thread. Kevin

Hello @colin , any news? I Noticed that this happens because the "real" gets recreated when the fixed header disappears (scrolling to the top). The regeneration of the thead lose the style attribute of the . Is there a way, by api or config, to avoid the recreation of the thead?

You have api.columns( 7 ).data().sum(); to get the sum. Use the selector-modifier of { search: 'applied' } like this api.columns( 7, { search: 'applied' } ).data().sum();. Kevin
