FillType

type FillType = typeof FILL_TYPES[number];

How a fill projects the seed cells into the destination, mirroring Excel’s fill-handle drag:

  • copy --- repeat the seed without progression.
  • series --- extend each numeric run as an arithmetic series.
  • linearTrend / growthTrend --- fit a least-squares line / exponential and extrapolate. Only offered when a run has two or more numbers (seedSupportsTrend).
  • default --- like series, but a single-cell plain number copies.
