barlowrm - Have a look at
Preferences->Look and Feel->Column icon (rightmost tab).
I would use
Icon with no text, on an integer column, and then make use of the template logic that yields 'Yes' or 'No', in an Advanced Rule template that yields 'green tick.png' or 'red cross.png'. The value of the integer column is irrelevant, it's just a hook on which to hang an icon (or more if you use "
Composed (i.e. multiple) icons with no text)
Then I would remove the composite column.
You must supply the icon images (a 128px square PNG is recommended, with transparent edges is best), I keep mine in a
myIcons folder in the calibre config directory. I can usually find something suitable here ==>>
