Struct Columns 

pub struct Columns {
    pub name: Rect,
    pub size: Rect,
    pub age: Rect,
    pub label: Option<Rect>,
}

Where the tree’s columns went, laid out once for the table and for the hit test.

Length constraints derived from these are what the Table is given, so the widget’s own split reproduces this one exactly rather than merely agreeing with it — which is the difference between a heading a click sorts by and a heading a click sorts near.

The rectangles cover the tree’s rows. The heading is a line above them and takes only the horizontal extent, which is the whole of what a column is: x and width are the column, and y is whichever band asked for it.

Fields

name: Rect

The mark box, the indent, the expander and the name.

size: Rect

What the subtree is worth.

age: Rect

How long ago it was touched.

label: Option<Rect>

What a claim is, when the terminal is wide enough to carry the column.
