I am trying to add a css class to a column in a tree view so I can adjust the columns and prevent page overflow. After doing some research, I determined that I needed to do one of the following:
<tree string="Products" class="myclass">
or
<field name="name" class="myclass">
Both of these are causing XML validation errors in the openerp console and, presumably, would do the same if I made a custom module. How can I set the class on a column in a tree view so that I can apply some custom css to it?
