)

Arguments

Details

This function is used in two different ways: (1) When adding base styles (i.e. named styles in the pivot table) to this `PivotOpenXlsxStyles` collection: In this case, `baseStyleName` is the name of the style and `isBaseStyle=TRUE` (so matching is by name only) and `style` is the `PivotStyle` object for the base style. (2) When finding styles that have been applied to individual cells using the `PivotStyle` object that is attached to each cell: In this case, `baseStyleName` may or may not be present, `isBaseStyle=FALSE` and `style` is the `PivotStyle` object from the cell.
