UI.Table

UI.Table(input: Input): Node

Creates semantic tabular data whose direct children are TableRow nodes. Assistive technologies can preserve row and column relationships that a collection of generic rows cannot express.

Mental model

This is a declarative node: app.render describes it again from current state, while the host matches its stable id to the existing view.

Before you use it

Add luastra/ui to this module's dependencies in luastra.json, then import it with require("luastra/ui"). The project must declare the ui.render capability. app.render must return one UI.Screen root; place this node inside that tree rather than invoking it for a hidden side effect.

How it fits

The constructor validates its fields immediately and returns a UI.Node. After app.render returns, the host reconciles that node by stable id with the current semantic DOM-based interface. Current desktop and mobile hosts package the same web artifact; native adapters are used at capability boundaries.

Shared parameter groups

Parameters

Children and layout

Table rows only.

Accessibility and keyboard

TableRow and TableCell create a real table; header and scope associate headers with columns and rows.

Common mistakes

• Using a duplicate id or an uppercase path segment.
• Passing a shared-group parameter that is not listed on this component page.

Returns

Node — a validated declarative UI node that becomes part of the next host-neutral render tree.

What happens next

A validated declarative node appears after it is returned as part of the current render tree.

Failures and fixes

Invalid fields, duplicate IDs, unsupported child combinations, or a missing ui.render capability fail during check, render-tree validation, or host startup.

Availability

Source API in 0.5.0-alpha; the public installer targets 0.5.0-alpha. Verify host-specific behavior against the selected SDK.

Focused example

UI.Table {
    id = "docs/parameters",
    label = "Parameters",
    UI.TableRow {
        id = "docs/parameters/header",
        UI.TableCell {
            id = "docs/parameters/name",
            text = "Name",
            header = true,
            scope = "col",
        },
    },
}
