how to apply css file to a column in grid?

i already have a css file with styles defined such as

date-col {
background-color: #def;
etc
}

amt-col {
background-color: #eee;
etc
}

how can i apply the style by name to columns in the grid? i only know how to do set individual style like this:

awGrid.getCellTemplate(col, row).setStyle("background-color", "orange");

but it would be nice to be able to apply date-col, amt-col rather than each attribute of it.

thanks

You can use setClass(name, value) method but your classes shoudl be named according to AW rules, i.e. .prefix-name-value, where prefix=aw

http://www.activewidgets.com/aw.system.html/setclass.html

for example,

.aw-col-date {
...
}

.aw-col-amt {
...
}

grid.getCellTemplate(i).setClass("col", "date");
grid.getCellTemplate(ii).setClass("col", "amt");

thank you alex!
