Edit/Create set operations allow sets to be created using a formula or text editor or edited in a spreadsheet-like fashion.
Edit is used to alter an existing set by invoking a spreadsheet-like editor. Values are updated by pressing return or when leaving a cell. Several buttons appear on the widget:
Add a point to a set by copying the currently edited cell and appending it directly afterwards
Delete the current point.
Change the format, precision and column widths of the table.
Refresh the display. This is useful if the set type changes or the number of points changes.
See Load & evaluate
Create a new set by invoking a text editor.
