editing form for individual cell

Hi Allan,
I am trying to make an attendance sheet and make entry through a form appearing on clicking each cell matches the employee and the date.
db tables i m using is an attendance entry( where date and other leave details are entered )
using the dom table (not ajax ) i made the table appearing and marked present or absent on it.

<th>Employee</th>	<th>Apr1</th>            <th>Apr2</th>            <th>Apr3</th>           etc 

Now I have to update the entry against each date for each employee using modal form. I could not edit whole row as it is not different fields but different records of same db table.
Can you please guide me for a solution. or is it almost impossible by data table editor?

thanking you
Vinod
