Do I have to create a new component for a matrix view?

[Kostas Karadamoglou]

Hello, I would like to create a component that renders a matrix 
according to the parameters "rows" and "columns". Each cell of the 
matric/table should be clicked and then programatically the programmer 
should extract the object which is mapped to this cell. Also the 
presentation of the cell depends on the object which is linked to. I 
think the html version of calendar is similar but with fixed row and column.

1)Does this component already exists?
2)If not, Which is the best approach, do I have to create a renderer or 
a component (may be rendering UIData component)?
3)If I have to create a component, Which component is it better to extend?
4)The  matrix component will be used  for a seating plan representation.
5)Any ideas, on how to do it with less effort?

Thank you in advance, kostas
