Select columns A:E and apply any Format > Autoformat styles... Killed the process after an hour. While the use case is to select only a small number of cells and to apply the style to this selection it's not unexpected that users try it for whole columns. A warning before the execution of potentially long lasting operation could be a solution. Or to disable the function in case of selection beyond a reasonable number.
Confirmed using LO 6.0.0.3 / Windows 7. Applying autoformat syles happens instantly in 5.4.0.3. => regression
Correction: it depends on if the style has row-alternate shading, eg. Box List Blue (6.0) or Currency Turqoise (< 6.0). When using the appropriate style, the bug occurs from 6.0.0.3 all the way back to 3.3.0.

Version: 24.2.2.2 (X86_64) / LibreOffice Community Build ID: d56cc158d8a96260b836f100ef4b4ef25d6f1a01 CPU threads: 8; OS: macOS 11.7.1; UI render: Skia/Metal; VCL: osx Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded in 24.2.2.2 (X86_64) / LibreOffice Community columns A-E take long, but format succeeds. Bug marked duplicate 124341 may not be a duplicate. "Selecting only part of the document works as intended." #124341 still fails. Difference in repro steps is "select all", instead of Columns A-E. This implies that the code is now more efficient, but not scalable to the default number of cells.
Thorsten Behrens committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/46f7dcc5f499892ef093147b3f739c258bbf6b81 related tdf#115474: improve warning msg for slow autoformat It will be available in 25.2.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
Possibly something like commit 15fd6de056a1389702a1d3be9ffd3fdd5a0795de could help here (unless that commit already applies? I haven't debugged).
(In reply to Commit Notification from comment #8) > Thorsten Behrens committed a patch related to this issue. > It has been pushed to "master": > > related tdf#115474: improve warning msg for slow autoformat FTR: commit 52b95cfbb0aba120229f9f92570f2aa6f1fe3e33 added the initial message to autoformat, that the commit above has improved.

While both have the same root cause, there are specifics that allow to have some special-casing in whole sheet case (or more specifically, whole rows case), which wouldn't affect e.g. whole-columns (not whole-sheet) case. Let me unduplicate.
It takes only 17 secs to apply Box List Blue to A:E. Should we close this?

Less with a fast machine but still more than acceptable. Although you get a warning before, no action should take more than 500 milliseconds. UX advise in this case is to run in background. But I believe we may have a chance to make the code more performant. My take is to keep the ticket.
(In reply to Heiko Tietze from comment #13) In theory, I agree. Just noting, that doing faster than now is only possible, if we re-implement the autoformat to be some true document model feature (and maybe file format feature), rather than the current "applying a direct format to the selection" thing. I don't mean to contradict you, just this further improvement may be worth a separate tracker.
We may widen the scope of this ticket to any DF formatting. Or request table styles as ODF inherent attribute. I'd appreciate both :-)
