Phase 0 - Editable rows with eSheets

[horner]

when edit is enabled, User used arrow keys and presses enter or double clicks or clicks a pencil on the row:

• Consider using github.com/mieweb/yorm for multi-presence collaborative editing (NOT datavis state)

• (make a eSheet from the columns and the types)

• update the data in the table

• push (send it to a server)

Developer could specify:

• eSheet to use for the row.
• onSave of the eSheet
• onSave of the DataVis. (this would allow someone to edit multiple rows and then push all the changes in in a single save)
