I can see plenty of posts about where the field description extended property lives and how I can get it, but nothing about adding these at the CREATE TABLE stage.

SQL Server provides a system stored procedure that allows you to add descriptions, one name-value pair at a time
Example as follows:
EXEC sys.sp_addextendedproperty
@name=N'Column 2 Description' -- Give your description a name
, @value=N'blah blah 2 for a specific column' -- Actual description
, @level0type=N'SCHEMA'
, @level0name=N'dbo'
, @level1type=N'TABLE'
, @level1name=N'MyTestTable' -- Name of your table
GO
You would have to repeat for each description name-value pair
Hope this helps
