Horizontal scroll on wide tables no longer works

[wwccscorer]

Tables with align:none which are too wide for the screen width no longer scroll horizontally but instead break words (word-break:break-word from .wp-block-column, inherited from div)
See ​http://www.sssccrrl.co.uk/2025-round-5/ on eg a phone for an example.
I can work around using custom CSS :-

.do-not-break-words {
  word-break: normal !important;
}

but this is not feasible to apply for all the historic data on my websites.

Hi and welcome to WordPress Trac!

The Column blocks come from the template (in this case, using Twenty Twenty-Three).

The word-break style was added in ​GB11904. That might need to stay there for everyone who uses Columns blocks inside individual posts, but you could open an issue about it on the Gutenberg repository.
​https://github.com/WordPress/gutenberg/issues

For now, I think you could add the following ​custom style:

.wp-block-column table {
  word-break: normal;
}

This behaviour has only started in the last month or so. Previously the tables would scroll horizontally as expected.
I don't have a problem with adding the custom css but I am puzzled why this has started happening.
There is already a (closed) issue on github (github.com/WordPress/gutenberg/issues/24393) which shows the expected behaviour for a default table. That is the behaviour which my tables previously displayed but now don't and display as break:word instead.

break-word from both Table and Columns styles with fixed layout table

Your site might have displayed differently at some time between last year and this month, but the results tables broke words in November and December 2024 (copies at archive.org).

• 2024 Round 8 had word-wrap from the ​Column block styles.
• 2024 Final Round was set to fixed layout, so it also had word-wrap on the ​table cells.

I'll close this ticket as 'reported-upstream' because GB24393 describes a similar situation, but any changes to the Columns block styles likely would need to be discussed on their own issue.
