Style CSS

Please,

I'm doing the update in one of our software how userd activewidgets v1 to v2, but I'm know how where I use the style CSS for my columns.

After I usede:

.active-grid-column {
   border-right: 1px solid threedlightshadow;
}

.acitive-grid-row {
   border-bottom: 1px solid threedlightshadow;
}   Now I try use:

.aw-grid-column {
   border-right: 1px solid threedlightshadow;
}

.aw-grid-row {
   border-bottom: 1px solid threedlightshadow;
}   but only rows it's work.

You can help me ?

Should be

.aw-grid-cell {...}

instead of .aw-grid-column

.aw-grid-cell {
text-align: right;
border-right: 1px dotted red;
}

Thank's
