The disabled parameter for a TabPane should disable a tab

[davep]

Consider this code:

from textual.app import App, ComposeResult
from textual.widgets import TabbedContent, TabPane, Label

class DisableTabApp(App[None]):

    def compose(self) -> ComposeResult:
        with TabbedContent(id="top-level"):
            with TabPane("One", id="one", disabled=True):
                yield Label("This is tab one")
            with TabPane("Two", id="two"):
                yield Label("This is tab two")

if __name__ == "__main__":
    DisableTabApp().run()

Note the disabled=True on TabPane. Widgets in Textual will go into disabled mode when disabled is set to True when creating them. It would be reasonable for a developer to expect this to happen here too but currently it doesn't.
