Hi,
I am implementing a JTable. Using TableModel and JScrollPane( the
usual).

JTable(32*3)
Vertical scroll bar ALWAYS
Horizontal scroll bar AS NEEDED

Problems:

1: Vertical scroll bar doesnt show up! What do i do?

2: I want to change the color of the table (not grid lines); its
background
i.e of all the individual cells. How?

3: For column 0 -- values are hardcoded(0 thru 31)
  For column 1 -- will keep changing
  For column 2 -- will keep changing

How do I do that? I know have to override getValueAt(), but what are
the first steps?

I do not want to make it user editable though.

Is Jtable right for the above?

4: Consider a JLabel. If I want to display a message to user and
depending on the action taken replace that by another message, 1 way
to do that is replace the old label by blank string then put in the
new message. Can't this be done in 1 step? Should i use anything else
that JLabel?

I am returning to Swing after 2 years. Thats why such newbie
questions. Have forgotten everything. :-(

Any help/comments are appreciated.

Sincerely,
