It would be convenient to be able to re-organize columns in Datatable. For example if I didn't add column B at the initial setup but did add columsn A, C, D, and I want this data later, I can't insert it where I expect to have this data.
This is more of an issue with several columns but the only workaround I've found is to remove the data, update the columns, and re-add all of it. Data table can't be extracted in whole so making this update is difficult and can lead to inaccurate updates.
