Dojo Spreadsheet Widget
Another reason to move towards the Dojo framework.
Judging by the source and functionality of the component, it looks like it could be on the path of becoming another Google Spreadsheet.
Some of the goals of the 1.0 version are:
- Fix all remaining bugs related to column, row resizing and selection
- Support cell presentation format (dates could be displayed as mm-dd-yyyy, numbers as xx.xx, etc)
- Support for date functions
- Post spreadsheet data in JSON format to be saved serverside
- Improve validation
It looks very impressive.
