By "basic table editing", I mean generic workflows not specific to Wikimedia projects. By "support", I mean make it possible, not necessarily user-friendly (although that's a desirable goal).
Rearranging rows and columns Cutting and copying parts of tables Pasting parts of tables as new tables Pasting parts of tables into an existing table Adding row headers Navigating between cells in a table using tab or arrow keys
It doesn't include the following (although they're desirable goals):
Making tables sortable
- Coloring table cells
- Making table controls which already exist more user-friendly
- Editing tables made up of templates
Finished tasks are
