Answer 1

I had this happen to me in the past and I was convinced it had to do with the Cell Renderer, but the ArraysXxxException kind of Exceptions hunted me because I had forgotten to unselect and stop editing the cell before adding/removing rows. You should try clearSelection() and table.getCellEditor().stopCellEditing(); on your JTable before remove/add and see if that solves your problem.

First, of course, make sure it is editing:

if (table.isEditing()) {
    table.getCellEditor().stopCellEditing();
}
