- 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
