Unwanted margin in multi-page table

[morloy]

We discovered a very strange margin issue in a table that spans over two pages.
As you can see in the image, one single number has a margin to the right. The HTML code for all rows is exactly the same. So I'm a bit confused about how to trace this bug. Maybe some of the experts can give a hint?

Here's the source HTML and the produced PDF from WeasyPrint.

Can reproduce the error and it's - - - STRANGE!
There seem to be magic numbers involved. Don't get it. Yet.

Stupid workaround at the moment:
Alter your @page's top margin. Either reduce it to 2.8cm or less. Or increase it to 3.2cm or more.

/* report.html, line 12433 ff */
    @page {
      size: A4;
      margin: 3cm 2cm; 
      /* margin-top between 2.9 and 3.1 produces the strange error */
      margin-top: 2.8cm;
      @bottom-right {
        font-family: 'Montserrat';
        content: "Page " counter(page) " of " counter(pages);
      }
    }

As I said: strange magic numbers. I keep at it and will report my findings.

What a dirty bug!

@morloy It's also the first real-life problem I get with flexbox, as I had to fix an endless loop before fixing this bug. I'd be really interested by some tests with your documents (as bootstrap includes some flexbox layout). If you can test the current master branch, it may avoid bad surprises when next version is released!

There seem to be magic numbers involved.

@Tontyna Thanks for the hint!

@liZe Cool, current master works with the sample document. Thanks a lot!
When will the fix be available in pip?

Yes, now that the bug is fixed 😉. It would be a good idea to test other (if any) documents you're generating too, as flexbox support may have broken /changed them.

When will the fix be available in pip?

I'll release another 0.42.x version before the end of the month.
