RowReorder example not clear to me if table.on('row-reorder') is required.

Description of problem:
It is not clear to me if in the Editor RowReorder example, it is required to use table.on('row-reorder'...)?

Are you referring to this example?

I don't see the row-reorder event used in that example. Please tell us which example you are looking at. And why you are asking about the need for row-reorder.

Sorry for the unclear question. In my project the ajax calls are not generated when the rows are exchanged.

I would guess that you haven't used rowReorder.editor in that case, but we'd really need a test case or at least sight of the code, to be able to say for certain.

Allen, I do have rowReorder.editor options filled in.

Ok. Other attemt to clarify my misunderstanding. I don't blame you by the way.

In the editor example, I can't see the code which I need to have to send the ajax requests for the update of the database. Or is it fully automatic?
At least, not my case.
I use now

table.on('row-reorder', function (e, diff, edit) {
              let result = 'Reorder started on row: ' + edit.triggerRow.data()[1] + '<br>';
...

to intercept the information which I can sent to the backend.

Its automatic if you have this:

        rowReorder: {
            dataSrc: 'readingOrder',
            editor:  editor
        },

Click on the Ajax Data tab and perform a row reorder. You will see the editor send the edit request with the ID's to change. And you will see the response from the server.

In this example, line 40 of the code block below the table you will see where I assign the Editor instance to rowReorder.editor. Editor has its own event handlers for that.

If you aren't using Editor, then yes, you would need your own event handler for row-reorder.
