Summary
In st.data_editor, when you dont have a value for a determined cell, it will be showed as None:
Why?
Since it is very user-unfriendly (a non-tech person may not understand what means None), it will be interesting have a parameter in st.data_editor that allows to replace these None by, for example, empty string (""), that will looks like this, but only for view purposes, without messing up the output.
How?
a parameter like:
none_alias=""
that allows me to change the None showing in the table.
