Auto Extend Filter Range

SpreadJS supports extending the filter range automatically by adding data or using copy-paste, drag-fill, and drag-drop actions below a filter range.

AutoExtendFilterRange will extend the filter range automatically below the origin filter range until there are all null values in the filter range columns. AutoExtendFilterRange can only work in a normal worksheet filter, and will not work in table/pivotTable/tableSheet filter. You can disable/enable the auto extend filter range by using allowAutoExtendFilterRange, which is false (disabled) by default. When the allowAutoExtendFilterRange is true, users can get the extended filter range by rowFilter.extendedRange;
