Highlight the row on mouseover

Hi, now i use .aw-mouseover-row {background: #def;}
to highlight the row.

But when i use aw.gird.extended , the row was seperated by 2 part, when the mouse is over the first cell of the row, just hightlight the first cell, when mouse over other cells, the first row isn't highlight.

So how can i get the seperated row but when highlight on mousevoer highlight the whole row?

Tks in advance.
