AutoFill and KeyTable how to disable click and drag from updating certain columns

Hello,

I'm trying out the trial version of the editor, specifically using the AutoFill and Key Table on my own project. There are certain columns that I do not want the click and drag feature from the AutoFill to update. My original work around this was to move all editable columns to the first 4 columns and all non-editable columns after the first 4 and used this:

    autoFill: {
        columns: ':nth-child(2),:nth-child(3),:nth-child(4),:first-child',
        editor:  editor
    },
    keys: {
        columns: ':nth-child(2),:nth-child(3),:nth-child(4),:first-child',
        editor:  editor
    }

This works great, but now there is a request to move 2 of the editable columns near the end of the table.

The problem with this is if you click and drag from the first column to either of the two editable columns that are near the end of the table it will update all the columns in between that I did not want to be selectable. Is there a way to avoid this, or should I just keep the selectable columns in the first 4 columns?
