Question

I have a JTable and I need to be able to reorder the columns. However I want the first column to not be able to be re-ordered. I used the following to enable reordering:

table.getTableHeader().setReorderingAllowed(true);

The columns can now be reordered including the first column which I don’t want. Is there any way to lock the first column?

I have seen some solutions that use two tables with the first column being in a separate table, but maybe there’s a better/simpler way.

Answer 1

I think that you need to override the columnMoved() method in TableColumnModelListener. the TableColumnModelEvent class has a getFromIndex() method that you should be able to look at to determine if it’s your fixed column, and then you should be able to cancel the event.

Hope that helps. A
