How to identity when drag starts and drag stop when using columnDrag as true

[LalitKushwah]

Hello JSpreadsheet Team,

Thanks for building the great project. It is very useful and I have a requirement where I need to collect the data which has been changed while using the column drag functionality.

I have gone through all the documents and haven't found any event which provides this information. Can you please guide me here? How can I achieve this?

Thanks a lot
