Table <tr> tag - style question

[jerryr125]

Hi - I know i can do this with CSS but unfortunately in the table I am designing I CANNOT use CSS.
Is there a way to a style to the <tr> table tag so that every other row has a different background ?
That is the odd rows have a grey background and the even rows have a green background (as an example).

<tr style=" ??? ">

Thanks - Jerryr
