PreferredCellSize の Width が 0 に設定される場合、UltraGridColumn.Width の値は幅として使用されます。Height が 0 に設定されている場合は、適度なデフォルトの高さが計算されます。
複数のセルの OriginX と SpanX が同じで（垂直に積み上げられており）、PreferredCellSize の設定が異なる場合、そのようなセルはすべて最大の幅で表示されます。同様に、複数のセルの OriginY と SpanY が同じで（水平に並んでおり）、PreferredCellSize の設定が異なる場合、そのようなセルはすべて最大の高さで表示されます。
MinimumCellSize プロパティが 0 より大きい幅のサイズに設定されている場合は、MinimumCellSize の幅と PreferredCellSize の幅のうち、大きい方がセルのサイズとして使用されます。同じことが高さにも適用されます。
