Apply a css style to a table ow based on the cell contents?

How could I apply a css style to a <tr> row based on the value of the contents in column 1?

For instance, on my table (generated from an asp:GirdView), column 1 contains a number ranging from 1.00 to 12.00. I need to show a certain background color for all rows whose value in column 1 is greater than 10.
