What pain point is this feature intended to address? Please describe.
Classical spreadsheets allow users to define formulas wherever they want. e.g., frequently, users will add formulas alongside tabular data to compute quick summary statistics (sums, countifs, etc...). Vizier's relational spreadsheet model does not make this easy, as each cell belongs to a strongly typed column.
Describe the solution you'd like
Provide a dynamically sized group of cells alongside the normal spreadsheet that can be used for quick back-of-the-napkin math. These cells can/should be stored with the spreadsheet, but will not be part of the actual dataset.
Describe alternatives you've considered
Adding a new column just for summary statistics can be viewed as "heavyweight".
