How do I format the attachment icon and display column heading?

[yumei]

I have a column in an app for uploading of attachment. Everything works, except for 2 minor things:

1. The column header doesn't display in inline view. I check the column settings - nothing unusual.

2. In the inline display, the attachment shows up with a 'document' icon. I'd like to give the icon a color, red or blue or whatever, but I can't get it to change color (using the normal steps of coloring texts).

Any tips would be greatly appreciated!
