Fix #1275, which had been closed as stale, and is now reopened pending the implementation of this PR. If there is a page break inside a defined print area, Excel may not render the print correctly unless the xml `brk` tag contains a `max` attribute. Libre Office renders it correctly. This seems like a bug in Excel (https://learn.microsoft.com/en-us/openspecs/office_standards/ms-oe376/b32ae11b-dee7-4dcb-9b46-a0feb32ce94f states that Office ignores min and max). PR #3345 (issue #3143) already addressed this problem by allowing the user to explicitly specify a `max` property in the PageBreak object. This PR eliminates the need for the user to make use of that kludge, by adding `max` to the xml whenever a page break is specified on a sheet with a defined print area. Xlsx Reader will now ignore the `max` attribute for row breaks, since it is no longer needed; it already ignores it for column breaks. The user may still set the `max` property if desired, just in case the new treatment is not adequate (I have not found a case where that is true). Two existing unit tests are very marginally changed because of this PR.
PhpSpreadsheet

Patreon
I am now running a Patreon to support the work that I do on PhpSpreadsheet.
Supporters will receive access to articles about working with PhpSpreadsheet, and how to use some of its more advanced features.
Posts already available to Patreon supporters:
- The Dating Game
- A look at how MS Excel (and PhpSpreadsheet) handle date and time values.
- Looping the Loop
- Advice on Iterating through the rows and cells in a worksheet.
And for Patrons at levels actively using PhpSpreadsheet:
- Behind the Mask
- A look at Number Format Masks.
The Next Article (currently Work in Progress):
- Formula for Success
- How to debug formulae that don't produce the expected result.
My aim is to post at least one article each month, taking a detailed look at some feature of MS Excel and how to use that feature in PhpSpreadsheet, or on how to perform different activities in PhpSpreadsheet.
Planned posts for the future include topics like:
- Tables
- Structured References
- AutoFiltering
- Array Formulae
- Conditional Formatting
- Data Validation
- Value Binders
- Images
- Charts
After a period of six months exclusive to Patreon supporters, articles will be incorporated into the public documentation for the library.
PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
