API for updating column descriptions in List2 #217

Open gferreira2 opened 2 months ago

gferreira2 commented 2 months ago

sometimes the number of columns in a table needs to change based on context: the number of axes in a designspace, the number of points in a glyph, etc.

could we have a proper API for this? something like List2.updateColumnDescriptions()

thanks in avance for considering it!

I want to add the following methods:

appendColumn(description)
removeColumn(identifier)
insertColumn(index, description)

It shouldn't be too hard to do. The _buildColumns method called during __init__ just needs to be refactored so that it can do the description to NSTable conversion at any time.

The most tricky part is matching the data model with the new identifiers: it could be a dict with associated keys or a nsobject with associated methods
