column CSS, global change

Hello,
I am trying to make a global change to all my columns. I want the text in every column to be right aligned. Problem is I do not know how many columns I will actually end up having. So, I can't just use the .aw-column-X thing because I dont know how many col's to prepare for. I tried looking at the CSS, but, I guess since I am using the free version (just testing), the CSS is unreadible. So, my question is, how do I make my global changes to my grid?

Just in case anyone needs to know I need to:
- set the text alignment
- set a border

You can use .aw-grid-cell (or #myGrid .aw-grid-cell)

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