Function table 

pub fn table<'a, R>(
    columns: &[Column<'a>],
    rows: &[R],
    sizing: &Sizing<'_>,
    style: &TableStyle,
    width: u16,
) -> Table<'a>
where
    R: AsRef<[Cell<'a>]>,

A described table, sized and narrowed for width.

Hands back a Table rather than drawing one. Selection and scroll live in the app’s TableState, and the row highlight is already set from TableStyle::selected, so a caller renders this with render_stateful_widget and gets the house selection without saying anything further.

width is the area the table will be drawn in, which is what narrowing is decided against. Pass the Rect width that frame handed back rather than the region’s own, or the table budgets for the two cells the edge took.
