How do you perform On Demand loading for DataTable rows?

[Delengowski]

Hello,

Textual looks like a great project, I am interested in using it, due to its portability. My one requirement is the ability to load rows to a DataTable on demand. I am familiar with Qts MVC methodology, and its QTableView has methods such as canFetchMore and fetchMore for on demand loading. Is there anything equivalent? Or some recipe to do this with Textual? I'm struggling to find if this is possible, except for one discussion that links to a 3rd party Textual extension. Seems to be not?
