Class AggregateCellRenderer

Writes the formatted text of a cell (areaModel.getTextValueAt) as a text node – never as HTML – in the label structure of a normal cell (.ge-table-label-div > .ge-table-label). AreaModelAggregateFooter uses it for its results ("1,234.5" instead of the raw 1234.4999999) and labels when the column has no footer renderer.

Example

// an own footer model that formats in getTextValueAt and shows that text
class MyFooter extends AreaModel {
  private readonly renderer = new AggregateCellRenderer();
  override getCellRenderer(_row: number, _col: number): CellRendererIf { return this.renderer; }
  override getTextValueAt(_row: number, _col: number): string { return "Σ 42"; }
}
