[jQuery] Moving table rows on the fly.

I have a table of a calendar that I have made and on clicking a button
I need to re-order the table so that the users selected start month is
at the top.
I have done this so far by re-drawing but this seems to be quite
intensive and was wodering if there was a better way of achieving
this?
Such as moving the element nodes effected from the top to the
bottom...if it is possible?
