Struct Table 

pub struct Table<'a, C: PixelColor, M: Clone> { /* private fields */ }

Vertically scrollable table of borrowed text cells with an optional header.

Build it with Table::new, set columns/data with Table::rows or Table::row, optionally add a Table::header, then enable scrolling with the same builders Column exposes. A tapped body cell emits the Table::on_select message carrying (row, col).

Implementations

impl<'a, C: PixelColor + 'a, M: Clone + 'a> Table<'a, C, M>

pub fn new() -> Self

Create a new empty table. Position and size are assigned by the parent via arrange.

pub fn width(self, width: impl Into<Length>) -> Self

Width sizing intent.

pub fn height(self, height: impl Into<Length>) -> Self

Height sizing intent.

pub fn id(self, id: WidgetId) -> Self

Set a stable base id so body cells can participate in focus traversal.

pub fn header(self, cells: &'a [&'a str]) -> Self

The header row, drawn above (and outside) the scrolling body.

pub fn rows(self, rows: &'a [&'a [&'a str]]) -> Self

Replace all body rows at once from a borrowed 2-D slice.

pub fn row(self, cells: &'a [&'a str]) -> Self

Append a single body row.

pub fn columns(self, columns: usize) -> Self

Explicit column count. Overrides the auto-derived width; useful when some rows are short.

pub fn striped(self, on: bool) -> Self

Zebra-stripe alternating rows (default true).

pub fn selected(self, row: usize, col: usize) -> Self

(row, col) of the cell to render highlighted. Host-driven — typically the value the last Table::on_select set.

pub fn on_select<F>(self, f: F) -> Self

where F: Fn(usize, usize) -> M + 'a,

Callback invoked with a tapped body cell’s (row, col). Without it the body cells are inert.

pub fn scrollable(self, dir: ScrollDirection) -> Self

Make this table scrollable on dir. Tables scroll vertically, so ScrollDirection::Vertical is the usual choice.

pub fn scroll_state(self, state: &ScrollState) -> Self

Supply the host-owned ScrollState read this frame. Implies scrolling (vertical by default).

pub fn scrollbar(self, mode: ScrollbarMode) -> Self

When the scrollbar is drawn.

pub fn snap(self, mode: SnapMode) -> Self

Snapping mode.

pub fn on_scroll<F>(self, f: F) -> Self

where F: Fn(ScrollMsg) -> M + 'a,

Callback mapping a ScrollMsg to the host message.

Trait Implementations

impl<'a, C: PixelColor + 'a, M: Clone + 'a> Default for Table<'a, C, M>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, C: PixelColor + 'a, M: Clone + 'a> Widget<C, M> for Table<'a, C, M>

fn measure(&mut self, constraints: Constraints) -> Size

Report the size this widget wants within constraints.

fn preferred_size(&self) -> (Length, Length)

Per-axis sizing intent set via .width(...) / .height(...). Containers consult this during layout to allocate fixed slots, query intrinsic sizes, and split residual space among Fill / FillPortion children. Default is Length::Fill on both axes.

fn arrange(&mut self, rect: Rectangle)

Commit the final rectangle, recursively arranging any children.

fn rect(&self) -> Rectangle

The current arranged rectangle.

fn handle_touch(&mut self, point: Point, phase: TouchPhase) -> Option<M>

Dispatch a touch event. Returns a message if consumed.

fn mark_pressed(&mut self, point: Point)

Set this widget’s pressed flag if point hits. No message emit. Containers forward to children. Default no-op.

fn collect_focusable(&self, out: &mut Vec<WidgetId>)

Append focusable widget ids in traversal order.

fn sync_focus(&mut self, focused: Option<WidgetId>)

Synchronize focused state against the runtime’s currently-focused id.

fn route_action(&mut self, target: WidgetId, action: UiAction) -> Option<M>

Route a semantic action to the widget with id target.

fn navigate_focus(&self, target: WidgetId, action: UiAction) -> Option<WidgetId>

Request a focus movement relative to target for directional actions.

fn focus_rect(&self, target: WidgetId) -> Option<Rectangle>

Rectangle currently occupied by the focusable target, if any.

fn focus_at(&self, point: Point) -> Option<WidgetId>

Focusable widget id at point, if any.

fn draw<'t>( &self, renderer: &mut dyn Renderer<C>, theme: &Theme<'t, C>, ) -> Result<(), RenderError>

Paint into renderer at rect.

fn widget_id(&self) -> Option<WidgetId>

Stable id of this widget, if it participates in focus.

fn is_focusable(&self) -> bool

True if this widget should appear in focus traversal.

fn handle_action(&mut self, action: UiAction) -> Option<M>

Handle a semantic action directed at this widget.
