Add option to disable column order preserving

[jared-jewitt]

Is your feature request related to a problem? Please describe.

It looks like in order for column dragging to work, a storeColumnsKey must be supplied to the table. This works fine, however I have a table in which users can dynamically add columns. When these columns are added by the user, I'd prefer for them to be rendered in the order specified in the columns array in the useDataTableColumns hook. Instead, they are always added to the right side of the table. I have a pinned ellipsis menu as the last column, and it would be nice to have it stay there when new columns are added.

Describe the solution you'd like

Perhaps introduce a new prop (preserveColumnOrder?) where users could set to false if they want to opt out of this default behaviour.
