Dear Community!
This is my last weekly report about my GSoC project.
Last week I was working with my optimization, and its unit tests. It has been successfully merged into master. This fix improved DOCX tables opening time via 20%. This fix caused a regression, where the direct character formattings in tables were copied and applied on paragraph level, when inserting a new row.
To explain the context: MSO Word uses a paragraph mark symbol (i.e the control character than can be configured to be shown), which is imported in Writer as a 0-length hint.
To fasten up the import of DOCX tables, the core applies the formattings from this 0-length attribute on paragraph level, directly before inserting a new row. All in all, to solve this bug, we needed to make sure, that we only copy the formattings, if it is from a 0-length hint. This solves the problem, as that identifies, that the direct character formatting, what we copy and apply on paragraph level, is something which is inherited from the improt of DOCX paragraph mark symbol.

This week I fixed the regression I mentioned above, and made a unit test for it too.: https://gerrit.libreoffice.org/c/core/+/120624
All in all, during the project, I fixed several annyoing bugs around the tables, table styles, and learned very much about LibreOffice, and about working on my own, dealing with stress and frustration. Besides the bugs, I made several notes, and partial-results on how DOCX import/export is working currently, and what difficulties we face when it comes to implement a real table style. Furthermore I got familier with the great community of LibreOffice, when I was chatting and asking for some help on the IRC dev channel. I thank for everybody, who helped me with my questions.
I must give particular credits, and many thanks for the enormous help what I got from my my mentors, Németh László, and Michael Stahl. They helped me through the entire project!
I am very thankful for the opportunity to participate in this project!
There is much work left to do, and I definitely will continue to work on LibreOffice.
