/**
 * Chart data table (`c:dTable` in `c:plotArea`), distilled from ooxmlsdk

 * A grid of the source values drawn beneath a cartesian plot. Cartesian charts
 * only (column/bar/line/area); Excel rejects data tables on
 * pie/doughnut/scatter/bubble/radar/stock. Round-trips for Excel; the
 * xlsx-preview renderer does not draw the data table.
 *
 * Intentionally not modeled (preserved on update, author via raw XML): `spPr`
 * shape/border styling, `txPr` font, `extLst`.
 *
 * schema-excluded: spPr, txPr
