Here is a fancy heading for the viewer Read Progress column:

Column header: ▂ ▃ ▅ ▆ ▇
Lookup name: read_progress
Description: To customize this, read the help for the reading_progress()
template function in the calibre User Manual
Template: {id:reading_progress()}

And below is a combined column that displays also the viewer annotation count:

Column header: Progress
Lookup name: progress
Description: Displays calibre viewer reading progress plus annotation count
Template: 

program:
rp = reading_progress($id);
ac = annotation_count();
prefix = '▂ ▃ ▅ ▆ ▇ ';
if ac then
prefix & rp & ' 🟨 ' & ac
else
prefix & rp
fi

Optionally, use a zero width space for the Progress heading name:
[​] <- it's inside the brackets.
