Add color to column property grid

Hey,

I am struggling with this problem for a while now. I have a property grid, and I would like to give the 1st column a background color.

The API Docs say that I can place a renderer on a column by retrieving it's columnmodel. But when I try to do that it doesn't work. Here is my code:

Code:

---

pgrid.getColumnModel().setRenderer(0, function(value, metadata, record, row, col, store){
    metadata.attr = 'style="background-color:#FF00FF;"';
    return value;
});

---

When I try to use the above method on an EditorGridPanel, it does work. It seems that I can't place a renderer on a column in a property grid. Is there a way to give the 1st column in the property grid a background-color ?

Why not use a simple css rule?

Code:

---

.x-props-grid .x-grid3-td-name {
  background-color: #f0f;
}
