Fixes: QuestPDF#517
Add support for dynamic column width.
This currently only works for cells that don't use row or column spanning.

Original pr: QuestPDF#867

@lol768 I have opened two pull requests. Could you have a look at them?
Would it also be possible to enable discussions for this project?

Thanks for the PRs and apologies for the radio silence - my GitHub notifications list is a bit of a mess. I've pencilled some time in my calendar to review these tomorrow.

@lol768 Have you already found time to review this pr?

@Lure5134 I am recovering from some surgery. Your PRs are on my radar, but they are not currently top of my to-do list.

Hi @lol768,

thanks for the new release!
I noticed, that the release notes contains both prs: 682b5ab#diff-86ce5e5acfa623cc5e115b3bf9967d4ba79e02807c64e8f76486d8f5b5a8d5c3R4
But only one pr is merged. This pr is unfortunately not included in the release.

Thanks for flagging, will look for 2026.1.2 👍

I'm having some issues getting NuGet to accept the snupkg at the minute, so the release isn't quite "done" yet in any case.
