CSS on column in Scorecard

Hello!

Can anyone tell me how to modify the css for a column on the scorecard component?  It appears I could just create a custom css class and assign it to the "Cell CSS Class" property but I'm not able to get it working.

Here is my custom class definition (I want the text to be blue and underlined to give the user a visual indication that they can "select\click on it")

.mySelectableColumnScorecard {

  color: blue !important;

  text-decoration: underline !important; 

}

Here is my assignment to the column in the advanced property sheet:

The only thing I have been able to do is modify the color to blue using the cell layout properties but there are no properties for underlining text that I can see.

Also, if I can figure how to modify the display of the column, how can I ignore applying the css to the footer row - which is not "selectable"??

Thank you!!
