I am using JDK1. 2 to create a program that uses SWING to generate a JTable. How would I go about manipulating the JTable so that I can select different selection combinations of rows and columns within the JTable like on a standard spread sheet.

At present the JTable only allows me to select entire rows.

Thanks.......

try calling setCellSelectionEnabled(true), setColumnSelectionAllowed(true), setRowSelectionAllowed(true) and setSelectionMode(JList.MULTIPLE_INTERVAL_SELECTION) on your table. That will allow you to select multiple non-contigious sections.

Call them on the table itself after you create it:

JTable mytable = new JTable();

mytable.setCellSelectionEnabled(true);
mytable.setSelectionMode(JList.MULTIPLE_INTERVAL_SELECTION);
mytable.setColumnSelectionAllowed(true);


like that.

That sounds too easy..... but it works apart from setSelectionMode(JList.MULTIPLE_INTERVAL_SELECTION); as JList seems to be an unknown variable.

what about one more import statement ? :)

import com.sun.java.swing.JList ;
(or
import javax.swing.JList;
)

Heh, yeah. that would work. You can substitute setSelectionMode(2) if you're using JDK1.2.

If the stuff all works like you wanted, why not grade the question?
