自动扩展筛选范围

SpreadJS 支持通过添加数据或在过滤器范围下方使用复制粘贴、拖动填充和拖放操作来自动扩展过滤器范围。

自动扩展筛选范围 会自动将过滤器范围扩展到原始过滤器范围之下,直到下面全是空值。 自动扩展筛选范围 只能在普通的工作表过滤器中工作,在 table/pivotTable/tableSheet 过滤器中不起作用。 您可以使用 allowAutoExtendFilterRange 禁用/启用自动扩展过滤器范围,默认情况下为 false(禁用)。 当allowAutoExtendFilterRange为真时,用户可以通过rowFilter.extendedRange获得扩展过滤范围;
