ResizableTableController class

Controller for managing resizable table column and row dimensions.

Provides programmatic control over table column widths and row heights with support for constraints, default sizes, and interactive resizing. Extends ChangeNotifier to notify listeners when dimensions change.

Example:

final controller = ResizableTableController(
  defaultColumnWidth: 100.0,
  defaultRowHeight: 40.0,
  columnWidths: {0: 150.0, 2: 200.0},
  widthConstraints: {1: ConstrainedTableSize(min: 50, max: 300)},
);
