Request to Bring Back DataFrame ouput for 'etable()'

Hi,

This is my first time opening an issue on Github. Please excuse me if my issue isn't well structured.

After updating from pyfixest v-0.22.0 to the latest release (0.24.2) I noticed that etable(models, type="df") no longer returns a DataFrame object and instead only returns a pandas Styler object. While the Styler object has its benefits , especially for formatting and layout, it lacks some of the flexibility that a regular DataFrame provides.

In particular, with a DataFrame output, I was able to:

  • Add custom rows with additional statistics. Although I realize this can now be done using the custom_stats option within etable() it allowed for more flexibility on the users' end.

  • Concatenate different etable results at a later stage in my workflow.

  • Easily export the table results to CSV format, which is important for some projects that require open-source data storage methods like CSV over Excel.

Request: Would it be possible to restore the option to get the results of etable() as a DataFrame (either alongside the Styler object or as an alternative option)? This would allow for greater flexibility in post-processing and exporting the results.

To keep my current project running without major changes, I’ve reverted to pyfixest v0.22.0, which still returns the etable(type="df) results as a DataFrame.

Thanks for you consideration and maintaining this amazing package ! :)

Hi Max @MaxTemmerman, thanks for raising this!

Sorry that we got rid of the df method - it was not on my radar that anyone would use it to store results! I suppose that you prefer etable over the tidy method because it also includes information on fixed effects, r squared etc? Coincidentally, @dsliwka and I chatted today about bringing back the "unstyled df", so that is what we'll do. =)

Thanks for the kind words, and excellent first issue! Thanks!

Hi Max (@MaxTemmerman), could you try out etable with output= "df" from this PR #614 and tell us if the output is as you'd like?

Hi Alexander (@s3alfisc),
Thank you for your response and for reintroducing this functionality! Although I'm no longer working on this project, I’ve shared this thread with a colleague who is still actively involved.

Thank Max @MaxTemmerman! New version with df output for etable is now merged to master.
