DataTable height: auto; does not account for horizontal scrollbar.

[aaronst]

This example creates a DataTable with a height of 2, but I think it should be 3 (header, row, and horizontal scrollbar).

from textual.app import App, ComposeResult
from textual.widgets import DataTable


class Test(App):
    DEFAULT_CSS = """
    DataTable {
        height: auto;
    }
    """

    def compose(self) -> ComposeResult:
        yield DataTable(id="table")

    def on_mount(self) -> None:
        table = self.get_child_by_id("table", DataTable)
        table.add_column("test")
        table.add_row("a" * 200)


Test().run()

I've been getting around this with min-height: 3;.

I'm not convinced this should be the case. It means the datatable widget will have to change its dimensions based on the visibility of the scrollbar.

I think in these circumstances you are better off setting the scrollbar to always visible

Closing as working as intended.
