Struct ColumnLayout 

pub struct ColumnLayout {
    pub order: Vec<String>,
    pub hidden: HashSet<String>,
    pub widths: HashMap<String, f32>,
    pub sort: Option<(String, bool)>,
    pub frozen: usize,
}

The user’s column arrangement — the widget WRITES this (header drag, divider drag, hide/show, sort click) and the consumer owns and persists it.

Fields

order: Vec<String>

Column keys in display order. Keys absent from the spec are ignored; spec columns absent from order are appended in spec order, so a consumer may start with an empty layout and get the spec’s order.

hidden: HashSet<String>

Column keys the user has hidden.

widths: HashMap<String, f32>

Per-column width overrides, in points.

sort: Option<(String, bool)>

(column key, ascending). None = the consumer’s own row order.

frozen: usize

How many LEADING columns are held fixed while the rest scroll horizontally. Counted over the arranged order INCLUDING hidden columns, so hiding a frozen column does not silently promote the next one into the frozen region. 0 = nothing frozen, one plain scrolling table.
