Using sp_send_dbmail to generate HTML-formatted emails

Have began using sp_send_dbmail in SQL Server 2005 to send me results of a query against one of our process schedule tables as an HTML-formatted email, using the following code :

DECLARE @tableHTML  NVARCHAR(MAX) ;

SET @tableHTML =
    N'<H1>Upcoming Process Schedule List</H1>' +
    N'<table border="1">' +
    N'<tr style="background-color: #5D7B9D; font-weight: bold; color: white;"><th>Year</th><th>Period</th>' +
    N'<th>ScheduledDate</th><th>SalesAnalysis</th>' +
    N'<th>Status</th></tr>' +
    CAST (
    (
    SELECT td = FY,       '',
                    td = PERIOD, '',
                    td = CAST(CREATED_DATE AS VARCHAR(23)), '',
                    td = SALES_COSTS, '',
                    td = STATUS
              FROM [SCHEDULEDB].dbo.tbl_schedules
              WHERE SCHEDULED_DATE >= getdate()
              ORDER BY SCHEDULED_DATE        
              FOR XML PATH('tr'), TYPE
    )
    AS NVARCHAR(MAX) ) +
    N'</table>' ;

EXEC msdb.dbo.sp_send_dbmail @recipients='raymurphy@somewehere.com',
    @subject = 'Upcoming Process Schedule List',
    @body = @tableHTML,
    @body_format = 'HTML' ;

This works fine, and sends me a nicely-formatted HTML email as expected. But out of curiosity, I was wondering what changes I would need to have the table rows formatted as alternate row colours or even if this would be possible using sp_send_dbmail as above ?

Thanks in advance.
