feat: table support for Excel (XLSX) sheets #282

wdoppenberg · 2024-09-03T09:30:28Z

Implemented functionality to read and work with named tables within Excel sheets. Updated .gitignore, added corresponding tests.

One note: I'm using a clone() in the build_table method, please advise on how to get rid of this. Also, please give me feedback on eager vs. lazy loading, I believe some refinement might be necessary there.

Related issue: #204

Oh wow thanks a lot! I'll review this ASAP. In the meantime, could you please rebase the branch and run make format ? Looks like a lot of code has been re-indented to 8 spaces, and we use 4

Thanks a lot for your work, looks great overall 🚀

Since it's a pretty big change, I'd like @PrettyWood to have a look as well, as I might have missed some parts (he'll be back from vacation next week).

Also, I wonder wether we should introduce a new type for tables: It'd allow us to store some extra metadata, and would allow us to add to_{arrow,polars,pandas} methods as well. As a nice side effect, it would also avoid the clone there currently is without needing changes on the calamine side

Anyway, this has motivated me again to polish the README and add some proper contributor docs 😅

src/types/python/excelreader.rs

+            // TODO: Remove clone
+            ExcelSheetData::from(range.clone()),


Here, I believe the best solution would be to submit a change to calamine: Either make the data field pub in or add a pub into_data(self) -> T method to the Table type

I've opened a PR: tafia/calamine#464

Can you update the TODO with "to update once calamine v.... is added"

@lukapeschke Yup I reckon we should differentiate Sheet and Table. I don' know if you want to work on that @wdoppenberg directly in this PR. It would be great but if you don't have the time we can merge this PR like that and work on a refacto after that on our end

I don't have time for this this week. So depending on your timelines you might want to merge and open a new branch. If you can wait a week I can spend some time then.

@wdoppenberg Let's merge this as is then to avoid more merge conflicts, and I'll see what I can do regarding the new Table object 🙂 Could you please give me push rights on your fork ? I'll fix the conflicts and merge the PR afterwards
