Description

save() to pdf gives junk output. The page looks like this in Okular:

Reproducible example

• [x] MRE: (just the README.md example with save() at the end)

import great_tables as gt
from great_tables.data import sp500

start_date = "2010-06-07"
end_date = "2010-06-14"

sp500_mini = sp500[(sp500["date"] >= start_date) & (sp500["date"] <= end_date)]

(
    gt.GT(data=sp500_mini)
    .tab_header(title="S&P 500", subtitle=f"{start_date} to {end_date}")
    .fmt_currency(columns=["open", "high", "low", "close"])
    .fmt_date(columns="date", date_style="wd_m_day_year")
    .fmt_number(columns="volume", compact=True)
    .cols_hide(columns="adj_close")
    .save("test.pdf")
)

test.pdf is the image posted above

Development environment

• Operating System: Ubuntu 18.04.6 LTS
• great_tables Version: 0.3.1
• Chromium version: Chromium 112.0.5615.49
• Selenium version: selenium==4.18.1

Additional context

(Yes, the Ubuntu and Chromium versions are old, it's at work and I can't do anything about it.)

Instead of Selenium could great_tables just use chromium-browser directly if it's installed? I'm able to output the table as html and then send that directly through chromium-browser --headless --print-to-pdf=output.pdf test.html. I suppose Selenium is more helpful if users have a different browser installed, though.

Hey, do you mind trying this with the latest Great Tables release (v0.6.1), and seeing whether it works for you? We overhauled the .save() method, and it looked okay on my machine (but I realize there's a lot of browser variation out there 😬 )

Still not working for me, using 0.9.0. (the output is nominally less garbage, as I can make out "S&P 500" but not really anything else)

Same Chromium and Ubuntu versions as above. Selenium v4.22.0.
