how to split a tableview cell into two?
<p>I like to create a cell like contacts's add instant messages table view, with two cells to select: "AIM" and "home".</p>

<p>May be I can use the custom table cell as the cell's content view, but the table view framework always treats 
one table view' cell as a whole, for example ,how to respond to did select row at index path message?</p>
