- Fix error on inserting columns or rows on the worksheet which contains one cell merged cell range
- Fix getting incomplete rich text cell value in some cases
- Unit tests updated
- Support set and get font color with indexed color
- New export variable `IndexedColorMapping`
- Fix getting incorrect page margin settings when the margin is 0
- Update unit tests and comments typo fixes
- ref #65, new formula functions: AGGREGATE and SUBTOTAL
- An error will be returned when setting the stream row without ascending row numbers, to avoid potential mistakes as mentioned in #1139
- Updated unit tests
This made a refactor with breaking changes:
Motivation and Context
When I decided to add set horizontal centered support for this library to resolve#1358, the reason I made this huge breaking change was:
- There are too many exported types for set sheet view, properties, and format properties, although a function using the functional options pattern can be optimized by returning an anonymous function, these types or property set or get function has no binding categorization, so I change these functions like `SetAppProps` to accept a pointer of options structure.
- Users can not easily find out which properties should be in the `SetSheetPrOptions` or `SetSheetFormatPr` categories
- Nested properties cannot proceed modify easily
Introduce 5 new export data types:
`HeaderFooterOptions`, `PageLayoutMarginsOptions`, `PageLayoutOptions`, `SheetPropsOptions`, and `ViewOptions`
Rename 4 exported data types:
- Rename `PivotTableOption` to `PivotTableOptions`
- Rename `FormatHeaderFooter` to `HeaderFooterOptions`
- Rename `FormatSheetProtection` to `SheetProtectionOptions`
- Rename `SparklineOption` to `SparklineOptions`
Remove 54 exported types:
`AutoPageBreaks`, `BaseColWidth`, `BlackAndWhite`, `CodeName`, `CustomHeight`, `Date1904`, `DefaultColWidth`, `DefaultGridColor`, `DefaultRowHeight`, `EnableFormatConditionsCalculation`, `FilterPrivacy`, `FirstPageNumber`, `FitToHeight`, `FitToPage`, `FitToWidth`, `OutlineSummaryBelow`, `PageLayoutOption`, `PageLayoutOptionPtr`, `PageLayoutOrientation`, `PageLayoutPaperSize`, `PageLayoutScale`, `PageMarginBottom`, `PageMarginFooter`, `PageMarginHeader`, `PageMarginLeft`, `PageMarginRight`, `PageMarginsOptions`, `PageMarginsOptionsPtr`, `PageMarginTop`, `Published`, `RightToLeft`, `SheetFormatPrOptions`, `SheetFormatPrOptionsPtr`, `SheetPrOption`, `SheetPrOptionPtr`, `SheetViewOption`, `SheetViewOptionPtr`, `ShowFormulas`, `ShowGridLines`, `ShowRowColHeaders`, `ShowRuler`, `ShowZeros`, `TabColorIndexed`, `TabColorRGB`, `TabColorTheme`, `TabColorTint`, `ThickBottom`, `ThickTop`, `TopLeftCell`, `View`, `WorkbookPrOption`, `WorkbookPrOptionPtr`, `ZeroHeight` and `ZoomScale`
Remove 2 exported constants:
`OrientationPortrait` and `OrientationLandscape`
Change 8 functions:
- Change the `func (f *File) SetPageLayout(sheet string, opts ...PageLayoutOption) error` to `func (f *File) SetPageLayout(sheet string, opts *PageLayoutOptions) error`
- Change the `func (f *File) GetPageLayout(sheet string, opts ...PageLayoutOptionPtr) error` to `func (f *File) GetPageLayout(sheet string) (PageLayoutOptions, error)`
- Change the `func (f *File) SetPageMargins(sheet string, opts ...PageMarginsOptions) error` to `func (f *File) SetPageMargins(sheet string, opts *PageLayoutMarginsOptions) error`
- Change the `func (f *File) GetPageMargins(sheet string, opts ...PageMarginsOptionsPtr) error` to `func (f *File) GetPageMargins(sheet string) (PageLayoutMarginsOptions, error)`
- Change the `func (f *File) SetSheetViewOptions(sheet string, viewIndex int, opts ...SheetViewOption) error` to `func (f *File) SetSheetView(sheet string, viewIndex int, opts *ViewOptions) error`
- Change the `func (f *File) GetSheetViewOptions(sheet string, viewIndex int, opts ...SheetViewOptionPtr) error` to `func (f *File) GetSheetView(sheet string, viewIndex int) (ViewOptions, error)`
- Change the `func (f *File) SetWorkbookPrOptions(opts ...WorkbookPrOption) error` to `func (f *File) SetWorkbookProps(opts *WorkbookPropsOptions) error`
- Change the `func (f *File) GetWorkbookPrOptions(opts ...WorkbookPrOptionPtr) error` to `func (f *File) GetWorkbookProps() (WorkbookPropsOptions, error)`
Introduce new function to instead of existing functions:
- New function `func (f *File) SetSheetProps(sheet string, opts *SheetPropsOptions) error` instead of `func (f *File) SetSheetPrOptions(sheet string, opts ...SheetPrOption) error` and `func (f *File) SetSheetFormatPr(sheet string, opts ...SheetFormatPrOption
- Close spreadsheet and row's iterator required
- New options `WorksheetUnzipMemLimit` have been added
- Improve streaming reading performance, memory usage decrease about 93.7%
According to issue #409
There is absolutely no reason for the timezone to be in UTC, and converting the local times to UTC while keeping values is hacky at least.
Excel has no understanding of timezones, hence the user of this library should know what timezone their values are supposed to be, by following the timezone within their timeTime structs.
* Support all datatypes for StreamWriter
* Support setting styles with StreamWriter
**NOTE:** This is a breaking change. Values are now explicitly
passed as a []interface{} for simplicity. We also let styles to be
set at the same time.
* Create function to write stream into a table
* Write rows directly to buffer
Avoiding the xml.Encoder makes the streamer faster and use less
memory.
Using the included benchmark, the results went from:
> BenchmarkStreamWriter-4 514 2576155 ns/op 454918 B/op 6592 allocs/op
down to:
> BenchmarkStreamWriter-4 1614 777480 ns/op 147608 B/op 5570 allocs/op
* Use AddTable instead of SetTable
This requires reading the cells after they have been written,
which requires additional structure for the temp file.
As a bonus, we now efficiently allocate only one buffer when
reading the file back into memory, using the same approach
as ioutil.ReadFile.
* Use an exported Cell type to handle inline styles for StreamWriter
