fix(tables): clear isColumnSelection on double-click and right-click, skip scroll for column select

- Clear isColumnSelection when double-clicking a cell to edit, preventing
  the column selection effect from fighting with the editing state
- Clear isColumnSelection when right-clicking outside the current
  selection, preventing stale column selection from re-expanding
- Skip scroll-into-view when isColumnSelection is true, preventing
  the viewport from jumping to the bottom row when clicking a column header
