I have this JTable and I have a Jextfield, both of which are in 2 different jPanels. I want the user to be able to click a certain cell in the jtable and get the value of the cell into jtextfield from the row selected but in the first column, regardless of what other column the user pressed. I don't see why when I get an error when clicking on the jtable...suggestions?
Thanks in Advance ^_^
