Help needed displaying rows

I have a simple DB table structure of 'Month' 'Week' 'Price'. If, for example I have 4 rows for Month 'January', and I want to output the following table structure from EZ Results:

[table]
[tr][td colspan=2]January[/td][/tr]
[tr][td]Week1[/td][td]Price[/td][/tr]
[tr][td]Week2[/td][td]Price[/td][/tr]
[tr][td]Week3[/td][td]Price[/td][/tr]
[tr][td]Week4[/td][td]Price[/td][/tr]
[/table]

I can see how simple it is to output the Week rows, but can't fathom out how to only display the Month row ONCE ONLY..?

Any help appreciated.
