Change row background color or banding

Question

Can I do such things in my table? I'm working with a table which formatted subtotal. Now, I want to change the row color of each subtotal row. However, I can't find any attribute of row to do it.
eg.
ID
10
Dept1 100
Dept2 100
Subtotal 200
20
Dept3 200
Dept4 300
Subtotal 500
Total 700
Thanks in advance,

Thanks Frank,
I'm using OA Components Page in Oracle Application. It's .XML extension(I think you know it). I tried some ways to change the row color such as set row attribute, and change rowFormats of table like this
processRequest
     tableBean.prepareForRendering(pageContext);
     //now get a handle on the array of Row Format Dictionaries
     DataObjectList myRowFormats = tableBean.getRowFormats();
     if(myRowFormats = null){
          DictionaryData[] myRowFormats = new DictionaryData[size];     
     //set the BANDING_SHADE_DARK property to TRUE for the second row
     //which corresponds to index 1 in the DictionaryData array
     rowFormats[1] = new DictionaryData(BANDING_SHADE_DARK,                          
Boolean.TRUE);
     //Modify any other row formats
     tableBean.setRowsFormats(rowFormats);
I found this on OAF Developer's Guide but it's not work out. Do you have any suggestion about it? Thanks for your time on this.
