Hide a column in JTable?

[Lim Wing Hoe]

How do I hide a particular column? I would still like to maintain all the
data for that column there, so that I can retrieve the selected data easily,
but I would like to have some columns that are not relevant to the user to
be hidden.

Set its width to zero. Or if you are never going to display it, don't even
include it in your table. Just have your table model provide only the
displayable data.

There are two or three methods of doing it.
1.Use removeColumnModel on the JTable. This wont remove the actual data from
the underlying tablemodel but only form the View the JTable. DIsadvantege
of this is that if you want to restore the column it becomes messy coding.

2.You can have an array of booleans saying whether each column is to be displayed
or not. Then you should override the getValueAt and setValueAt,etc functions
of the tablemodel so that the correct column number is used - for the column
number passed by the JTable will be with respect to the columns displayed
while the tablemodel's data Vector(or array) will be having more values.
Search in codeguru.com for a full sample of this.

I personally feel that method two is better.

Ramkumar,
Thanks for replying. I've been analyzing the same theory that you mentioned,
method 2. I will try to do this.
Oh yeah, I've just sent a reply to the message "How to listen to JTable
events?". I've written a piece of code near the end of the message in
regards to how I'm gonna retrieve the data. Do you think it will work?
