ColumnConfig Numbercolumn Localized

Using Streamlit
, ,

Hi ,I’m running my app locally but st.column_config.NumberColumn(format = 'localized") does not seem to be working as I expected. I expect the result of this minimal example:

# Set the locale for the number format NL
locale.setlocale(locale.LC_ALL, 'nl_NL.utf8')

# Create a title for your app
st.title('Minimal Work Example')


st.data_editor(
    data=pd.DataFrame({"A": [123994, 23445, 345446]}),
    key='data_editor',
    column_config={
        "A": st.column_config.NumberColumn(format="localized")
    }
)

To show a thousand seperator as a . and the comma as a , but instead it does not do that while when I print a number using this locale setting it does.
Streamlit version 1.43.2

Thanks for all the help in advance! I really need to tackle this issue before being able to make a streamlit app in production in the Netherlands since it can get very confusing for big numbers.

I have the same issue. It would help so much if you could change the decimal separator to a ‘,’

I was indeed missing something. The localization depends on the user browser language settings.

I think they just called localized to formatting the number with a period as a decimal separator and a comma for the thousands, I do not think the app is actually aware of the users’ locale.

Though I might be missing something, this exact issue was raised here and it was closed with the 1.43 release.

If the other options aren’t working, try replacing ‘localized’ with the following string below:

“%'d\n”
