Support table widget

[isidorn]

On top of the list widget we should build a table widget.
Same as the list it should be virtual and accessible.

Use cases:

• tabular variables view for debug
• ports view for remote
• problems view

Did not have cycles for this feature request this milestone.
Moving to August, since in July I am on vacation.

@joaomoreno bounced some ideas off me, but I did not get any further. For now pasting ideas here

/**
 1. use the listview to render a table in which every column has the same width
 2. have the header row be a splitview widget acting as a single point of truth for column sizes and have dynamically genereated CSS which reflects those sizes, such that element rows can adapt to them
 3. think about all widget features: focus, selection, keyboard & mouse, accessibility, themeing

  readonly label: string;
  readonly weight: number;
  readonly renderer: IListRenderer<R>;

}

  get columns(): Column<T, any>[];
  set columns(columns: Column<T, any>[]);
  setSelection(selection: { element: T, column: number }[]): void;
  getSelection(): { element: T, column: number }[];
}
// example
const nameColumn = {
  label: 'Name',
  renderer
  project(el) {
    return el.name;
  }
}
const model = [
  { name: 'fibonacci', type: 'ndarray' },
  { name: 'inxed', type: 'ndarray' },
  { name: 'msg', type: 'ndarray' },
  { name: 'n', type: 'ndarray' },
  { name: 'x', type: 'ndarray' }
];
// rendering
CSS
.table-col[data-col="1"] { width: 100px; }
.table-col[data-col="2"] { width: 150px; }
.table-col[data-col="3"] { width: 200px; }
<div class="list-row">
  <div class="table-row">

Due to the change in plans we do not plan to tackle this. Thus closing this as out of scope
