I have developed a roster for staff. Weekends and public holidays are defined by heavy vertical lines. Each cell has a drop down selection for rostered on, rostered off, etc. However, users are dragging cell entries to fill in up to ten days at a time. When cell contents are dragged, the cell borders (denoting weekends, etc) are also dragged to inappropriate locations.
Is there a way to protect cell borders while allowing cell contents to be dragged to new locations?
