  #### Describe the solution you'd like
  Tabulator has a left/right click context menu feature where callbacks can be registered. Having a context menu option for rows and cells would let the developer provide multiple options to perform additional operations/computations/visualizations/etc. This feature would be an amazing addition for providing a wide range of options for interactive data analysis.
