FdcProgressColumn renders numeric values as compact progress indicators. It is ideal for completion percentages, quality metrics, utilization, and similar progress-like signals.

    FdcProgressColumn(
      fieldName: 'completion',
      width: 180,
      progressMax: 100,
      progressTextBuilder: (value) => '${(value ?? 0).round()}%',
    ),
    FdcProgressColumn(
      fieldName: 'quality',
      width: 180,
      progressTextBuilder: (value) => '${(value ?? 0).toStringAsFixed(1)}%',
    ),
