Select Cell on a Grid

Hi,
I have the following problem
I Have to represent the 24 hours in a "grid". with 2 rows. The first
row contain the Hours o'clock, and the second row the half hours.
--------------------
1 | 2 | 3 | 4 |
--------------------
1.30|2.30|3.30|4.30|
--------------------

I need to select single cells in this grid, but the selection is not
consequential.
I tried to use the JTable, but searching on the web, I found that with
JTable is not possible to select non consequentials single cells. For
example I need to select the cell "2" and the cell "4.30".

How can I do it?
Does anybody can suggest me a component that can help me to do this if
the JTable is not the right way?

Thank you
Alessandro Rossi

Isn't the selection mode of DefaultListSelectionModel set to
MULTIPLE_INTERVAL_SELECTION by default? Or you can use setSelectionMode
to set it. Either way, you can then make non-contiguous selections.

Yes, but if you select for example the cell (0,0) and the cell (10,10)
you'll select all the cells between 0,0 and 10,10 beacuse they aren't
on the same row. The MULTIPLE_INTERVAL_SELECTION works properly only
if you are on the same row (or on the same column). That's what I have
understood.

I see now what you mean. MULTIPLE_INTERVAL_SELECTION allows one to
select rows 1, 3 and 5, or columns 2 and 4. But you need row 1, column 2
and row 2, column 5, for example.
