How to hide columns in JTable so that they can still be accessed using tableModel.getValueAt(row,colHidden)?

I did that way, but then I was unable to access 6th column using tableModel.getValueAt(row,6):

tbl.getColumnModel().getColumn(6).setPreferredWidth(0);
tbl.getColumnModel().getColumn(6).setMinWidth(0);
tbl.getColumnModel().getColumn(6).setMaxWidth(0);

Error message is:

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 6

Answer 1

RecvCallsTable.getColumnModel().removeColumn(RecvCallsTable.getColumnModel().getColumn(5));

This will remove the column from the model, i.e, from the user’s view but still be accessible using the index value. I use this all the time and it works perfectly
